Recommended List of EMF Meters and Instruments

For those of you who would like to take your own measurements of EMFs in your home or office, I have put together the following list of recommended affordable EMF meters and instruments that will give you reliable readings of the various EMFs that we consider to be potentially harmful. Naturally you can spend much more money than you would need to purchase the meters I recommend below, and if your budget allows this, you should certainly do so. More expensive meters don’t have the limitations that some of the meters below do have, however the meters mentioned below will give you accurate readings for home use.

These are the recommendations of Oram Miller, BBEC, EMRS. While they are based upon the meters and instruments generally recommended by the Building Biology Institute (BBI), the list below is not specifically endorsed by the IBE.

To take EMF measurements in and around your home, you will need four different instruments to accurately measure the four different EMFs that the building biology profession recognizes:

  • 60 Hz AC magnetic fields
  • 60 Hz AC electric fields
  • Radio frequencies
  • Voltage spikes of harmonic frequencies of 60 Hz, also known as “dirty electricity”

Once you have gathered your instruments, you will want to know what we consider to be safe exposure levels to these EMFs. Our profession has developed safe exposure guidelines since 1987 in Germany and they are now in their seventh revision. These Building Biology Evaluation Guidelines were developed specifically for sleeping areas, and they are broken down into four levels of concern for the first three types of EMFs listed above (the German building biologists did not develop safe exposure guidelines for “dirty electricity,” but I give those values below).

The four levels of concern are “No anomalie,” Slight anomalie,” “Severe anomalie,” and “Extreme anomalie.” Since these standards are quite stringent for the vast majority of our clients, including most electrically hypersensitive (EHS) people, we feel comfortable getting most of our clients out of the “Severe concern” range. Only the most highly EHS people need to try to achieve getting into the “No concern” level, a goal that is generally not easy or is impossible to reach.

For the vast majority of people, getting somewhere into the “Slight concern” level will be quite healthy for them, as these levels are on a par with the general consensus for EMF exposure among non-industry EMF experts and researchers around the world. For instance, the “Slight concern” level for AC magnetic field exposure in the building biology profession is 0.1-1.0 milliGauss (mG), while the generally accepted safe magnetic field exposure level according to most experts is 1-2 mG.

To download and print out the building biology safe exposure guidelines, click here. Generally speaking, the safe levels we try to achieve are less than:

  • 1.0 milliGauss (mG) for AC magnetic fields
  • 100 milliVolts (mV) for AC electric fields
  • 10 microWatts/meter squared (uW/m2) for radio frequencies while you sleep (I was also taught to try to get clients below 100 uW/m2 in the daytime)
  • 25-50 Graham-Stetzer Units (GSU) for “dirty electricity”

These are the ideals. It will be a challenge to achieve these safe levels in some circumstances, and easy to achieve them in others. I discuss how we can help you do that after describing the meters and instruments used for each type of EMF.

Oram Miller’s EMF Meter Package from LessEMF

In collaboration with Sean at LessEMF in New York, I have created a group of EMF meters that provide a very good measure of each type of EMF that the building biology profession recognizes. These are not the most inexpensive meters available, but I chose them because they will provide reliable, easy, repeatable assessments of the levels of these potential hidden sources of ill health in your home and help insure the safety of your living and work environment. If you can afford them, these are the meters that I ideally recommend for the person who wants to hire me for a long distance EMF evaluation of your home (when a local building building biologist is not available).

If you already have certain meters, you may want to upgrade (depending upon how well the meter you have measures the EMFs that we consider to be important) or just get the meters you don’t already have.

The four meters are as follows:

You can order these meters separately from the links above (there is no discount for ordering them together as a package). Or, you can call LessEMF at 518-608-6479 or 888-LESS-EMF (888-537-7363) and ask for “Oram Miller’s EMF Meter Package”. If the sales representative does not know of that, ask them to ask Sean.

I explain each meter in detail in the respective sections below for each EMF type. More affordable choices of meters to measure each of the four types of EMFs, as well as information about each type of EMF and other retailers who also sell great meters, are presented below.

AC Magnetic Fields

Magnetic fields are considered by us to be the most serious type of EMF, but fortunately, with the exception of magnetic fields from overhead power lines, they are generally localized to only certain parts of the house and are the least common of all types of EMFs. However, when you find them, you must deal with them because they are the most harmful EMFs we deal with. I say to clients that magnetic fields wear you down, causing a depressing influence on the immune system, compared to electric fields, which wear you out and rob you of a good night’s sleep. Magnetic fields cause a serious influence on your vitality and are known to be carcinogenic.

To read more about the potentially harmful health effects of exposure to magnetic fields and the scientific research to back this up, click on Article on Magnetic Fields and EMF Research Citations.

Magnetic fields are caused by:

1. Overhead power lines, for which there is nothing you can do; if the levels are consistently above 1-2 milliGauss wherever you measure in certain parts of your house, you must move where you sleep to another part of the house where they are lower, or, if that is not possible or the readings are high everywhere, you must consider moving altogether.

2. Electric current on the grounding paths of your electrical system, including the water service supply pipe and cable TV cable sheathing. These can be completely eliminated by installing a dielectric union and proper grounding to keep you in code; by using a non-metallic water pipe material if you are building new; and by installing a ground loop isolator if you have current on your cable TV cable sheathing.

3. Wiring errors on branch circuits in your walls, floors and ceilings, which need the services of an electrician who works in conjunction with one of us to trace and repair. These, too, can be completely eliminated.

4. So-called “point sources” of magnetic field exposure, including transformers and electric motors. Fortunately the magnetic field around these sources, while high close in, drops off by the inverse cube law, meaning it decreases quite rapidly, usually within a foot or so around most sources. Unsafe levels are only seen within 1-2 feet around most plug-in transformers and within 3-4 four feet around a refrigerator when the compressor motor is running. Electric clock radios have a field of 1-2 feet due to the transformer inside (or 3 feet if the hands move around a dial, due to an electric motor). Electric wattmeters and breaker panels have a magnetic field of 3-4 feet due to separation of conductors inside of them.

I suggest that you read my article on magnetic fields on my website here, found on the EMFs page, before you begin measuring magnetic fields. That way you will have a clear understanding of what they are, how they are produced, how they affect human health, what we consider to be the safe levels (compared to what electric utilities and governmental agencies around the world say is safe), and what we do about them. You will find our building biology safe exposure guidelines on my website by clicking here. Generally the consensus is to have magnetic fields below 1-2 milliGauss (mG), and as close to or below 0.5 mG in sleeping areas, where possible.

To measure magnetic fields, you have a choice of purchasing single-axis or triple-axis Gaussmeters. You can also purchase meters that only measure magnetic fields, and meters that measure magnetic fields and other types of EMFs, so-called “combination meters.”

With triple-axis Gaussmeters it does not matter what orientation you hold the meter in to give you an accurate magnetic field reading. This is because it has three bars within it placed in three different orientations, and the readings from the three bars are calculated together by the meter to give one composite number (a “True RMS” Gaussmeter).

With single axis meters, on the other hand, there is only one measuring bar within it, meaning you have to orient the meter the right way to get a meaningful number. Therefore, if you happen to get a high magnetic field reading in one orientation and then rotate the meter 90 degrees off axis, the needle or digital reading will drop, even though you have not moved the meter away from the source. Thus, if you choose to use a single-axis Gaussmeter, you must be careful to orient it in all three orientations wherever you are measuring to avoid missing an elevated magnetic field. See below for more on this.

The trade off is that single-axis meters are more affordable, generally less than $100, while triple-axis Gaussmeters are $199 to $300 and up.

It is my general recommendation that if you can afford it, you would be wise to spend the extra money to purchase one of the following triple-axis Gaussmeters, depending upon your budget. All meters are available from LessEMF:

For those who want to help differentiate magnetic field sources between 60 AC wiring errors vs. higher frequency magnetic fields from dirty electricity, such as from dimmer switches, purchase the 3-Axis Gaussmeter that Ignores Powerlines from Less EMF (known as the Magnii DSP-523) for $319. This is the Gaussmeter that I used for years (now I use the Gigahertz Solutions NFA1000). You can find the Magnii DSP-523 by clicking here.

Comparing Triple Axis Gaussmeters with Older Tri-Field Model 100XE Meters (and the New Digital Tri-Field Model TF-2)

I recommend one of the Gaussmeters listed above for measuring AC magnetic fields rather than the less expensive older Tri-Field Model 100XE combination meters (sold for $149), which are also triple-axis Gaussmeters (however, I do use and recommend their new, digital Tri-Field Meter, Model TF-2 and love it–see below). This is because as I understand it, Alpha Labs, the maker of the Tri-Field model 100XE meter, designed it to measure AC magnetic fields from any source from 50 Hz all the way up to 100,000 Hz (or 100 kiloHertz, kHz). This includes magnetic fields from wiring errors and current on ground paths such as metal water pipes and TV cables, which are causes of harmful health effects, but it also includes the magnetic field component of so-called “dirty electricity,” which occurs at frequencies up in the thousands and tens of thousands of Hertz.

I also understand that Alpha Labs favors the natural inflation of the actual magnetic field reading on their Frequency Weighted Tri-Field 100XE models, up to four times the actual number, when measuring sources of magnetic fields at higher frequencies of dirty electricity. That is what is meant by the term “frequency weighted.” As the frequency of the source increases, the natural distortion of the reading of magnetic field exposure on an analog Gaussmeter increases. Again, I am told this is acceptable to some because it brings the potential severity of the presence of these frequencies of dirty electricity to the attention of the homeowner and hopefully they will take steps to mitigate it. We don’t disagree with that goal, and this is also a position taken by many in the EMF Safety Community.

This is understandable and reflects the common viewpoint outside the building biology profession that dirty electricity is one of the most harmful types of EMF. In contrast, we in the building biology profession take a different view. We place dirty electricity lower on the list of four types of EMFs in terms of its potential harm to the general population, positioned after the other three. Granted, if one is electrically hypersensitive, dirty electricity will bother you and there are people who are quite sensitive to that particular type of EMF. We also acknowledge how potentially harmful dirty electricity can be for the general population.

However, we believe that the other three types of EMFs (AC electric fields and AC magnetic fields from house wiring, and radio frequency EMFs from wireless technologies) are actually more harmful to the population in general and even among those in the electrosensitive community. This is based upon our actual experience in the field. If you don’t look for the other types of EMFs, especially AC magnetic and electric fields at 60 Hz the way we do, you won’t find them. We find that they are exceedingly common and the vast majority of our clients, most of whom are electrically sensitive and symptomatic, report marked improvement in their overall EMF-related symptoms when we find and clear up these 60 Hz AC magnetic and electric fields, especially where they sleep. This is without a great deal of emphasis on dirty electricity, which we do also measure and mitigate. We can debate this issue further, but that is our experience in the field.

As a result, we put our emphasis on finding and reducing these other forms of EMFs, not to the exclusion of dirty electricity, but we don’t put dirty electricity above other EMFs.

We therefore have not used older Tri-Field Model 100XE meters when we report our AC magnetic readings to our clients. We use a True-RMS triple axis Gaussmeter for that purpose. Some of us do use the Tri-Field 100XE Frequency Weighted meter for what we refer to as a magnetic field “detector”. This is because the analog needle does swing up in the presence of magnetic fields, alerting us to their presence, along with the sound on our buzz stick. (The Gigahertz NFA1000, which I now use almost exclusively, also has noise that goes up when in the presence of higher magnetic and other fields, and so does the new digital Tri-Field TF-2 meter. This is a useful tool, hearing when the field strength increases audibly so you don’t have to constantly watch the display as you move around taking readings.)

I used to carry both a Magnii DSP-523 True-RMS Gauss meter and my Tri-Field 100XE Frequency Weighted meter set to the 0-3 mG magnetic field setting in one hand, and my buzz stick with an earphone in my ear in the other when hunting for 60 Hz AC magnetic fields in a home EMF assessment. (Now I use the Gigahertz Solutions NFA1000 3-axis Gauss meter and electric field meter to measure AC magnetic and electric field EMFs, available from Safe Living Technologies. The NFA1000 has it’s own built-in sound generator to let you know audibly how strong the field is, so I rarely need my buzz stick anymore.)

This is why we often measure AC magnetic fields readings lower than our clients who only own an older Tri-Field 100XE meter. If you own a frequency weighted Tri-Field 100XE meter, just be aware of this phenomenon. Alpha Labs does sell what they call a “Flat Response” model of the Tri-Field 100XE meter, identified by the words, “Flat Response” on the bottom of the back of the meter (known on the LessEMF website as the “Flat Frequency” model). Most older Tri-Field 100XE meters sold on the market are frequency weighted. If your Tri-Field 100XE does not have the words, “Flat Response” at the bottom of the decal on the back, yours is a Frequency Weighted model.

You will therefore have this distortion (in our opinion) of the magnetic field reading if dirty electricity is present, which is often the case. Special magnets are inserted into the Flat Response Tri-Field 100XE meter to dampen this exaggeration of the reading at higher frequencies. I have compared a Flat Response Tri-Field 100XE Gaussmeter with my Magnii DSP-523 True-RMS Gaussmeter, and the readings were virtually identical. Thus, if you are going to rely on the numbers from a Tri-Field 100XE meter, only use the readings from a Flat Response model. You can order a Flat Response Tri-Field 100XE meter by clicking here. However, Tri-Field now has a new digital version of their meter with several important upgrades. See below for details.

When we look for elevated magnetic field readings on our EMF evaluations, we are particularly interested in knowing if wiring errors or current on grounding paths are present, not dirty electricity. This is because we believe they are, in fact, the most harmful sources of the four tupes of EMFs. Dimmer switches and CFLs do make the needle of the Tri-Field meter and the number on the digital display on a True-RMS Gaussmeter go up when dimmers and CFLs are turned on and the Gaussmeter is held one foot or more away from the wall. So do the more serious forms of magnetic fields, wiring errors and current on grounding paths.

Distinguishing between them is important in our work because if I see an elevated magnetic field reading at a home I am evaluating, I need to know whether to bring in an electrician or plumber to fix a wiring error or have a dielectric union installed in the water service supply pipe, versus telling the client the elevated magnetic field reading on their Tri-Field meter they are so concerned about is only due to a dimmer switch. Contact me for more details on how we can help you make this distinction.

The True-RMS triple axis meters recommended above, unlike the Frequency Weighted Tri-Field 100XE Gaussmeter, are designed not to inflate the reading when measuring magnetic fields at higher frequency levels. They also measure magnetic fields within a more circumscribed frequency range. They will help you differentiate between elevated magnetic fields simply from a dimmer switch versus a more serious wiring error or current on your water pipe.

The magnetic field readings from a True-RMS Gaussmeter will also be more in line with readings obtained by EMF experts with the local electric utility and when comparing your home’s EMF levels to internationally accepted safe exposure levels for AC magnetic fields. That is why I recommend you ideally spend an additional $50 to $100 and purchase one of the models recommended above. If you cannot afford that, then now you can purchase the new digital Tri-Field TF-2, used in “Standard Mode”.

Measuring AC Electric and Radio Frequency EMF Levels with Older Tri-Field Meters (Model 100XE)

If you do own an older Tri-Field Meter model 100XE, it is called “Tri-Field” because it does have the ability to measure magnetic, electric and radio frequency fields (which is why it is called a “combination meter” in the LessEMF catalogue). While that is true, we have only recommended using it for detecting the presence of magnetic fields, and using other EMF meters to measure the electric and radio frequency levels. That has, as mentioned, changed with the new digital version of the Tri-Field, the Model TF-2, reviewed below.

This previous position was held because, first of all, the Tri-Field 100XE meter set in the electric field setting still measures near zero when the body voltage meter or other hand-held electric field meters show what my profession considers to be harmful electric field exposure levels, particularly where you sleep. Unfortunately, the Tri-Field meter is just not sensitive enough to measure this important but highly overlooked type of EMF.

We consider 10 Volts/meter (V/m) to be the beginning of the extreme concern level in sleeping areas, yet the number “1” on the top scale of the Tri-Field 100XE meter, used for measuring electric fields, represents this 10 V/m value. (This equates to 1,000 milliVolts on the body voltage meter.) Unfortunately, it is very difficult to measure down at the 1.5 V/m level (100 mV) or below that we consider to be safe with the Tri-Field 100XE meter. That would be down at 0.1 or lower on the top scale, which is not easy to see.

So in my opinion, the older Tri-Field 100XE meter is unfortunately not reliable as a way of measuring electric fields, however their new digital model is (see below). See the Electric Field section below for recommended meters for reliably measuring electric fields where you sleep, and elsewhere in your house.

Secondly, the lowest number you can read on the older Tri-Field 100XE meter when measuring radio frequency fields is 0.1 milliWatts/centimeter squared. While this is 100 times lower than what the Federal Communications Commission (FCC) considers to be safe, which is 1.0 milliWatt/centimeter squared, it is equivalent to 100,000 microWatts/meter squared in the unit of measurement that most of the world and our profession uses. This level is substantially higher than what my profession and other agencies and researchers, such as reported in the Parliamentary Assembly of the Council of Europe, consider to be close to a safe exposure level. For us, that level is down at 10-100 microWatts/meter squared, six orders of magnatude lower than what the FCC considers to be safe, and unfortunately, three to four orders of magnitude lower than the lowest reading possible on the Tri-Field 100XE meter. See the section entitled, “The FCC Versus the Rest of the World” in my Article on Radio Frequency EMFs page for more information.

Therefore, I only recommend using the Tri-Field 100XE meter, if you have one, for detecting magnetic fields (and using a True-RMS Gaussmeter, or Flat Response Tri-Field model, or their new Tri-Field TF-2 Meter for determining actual magnetic field readings) and I recommend using other meters for measuring electric and radio frequency fields, including their new digital meter. I am not trying to disparage Alpha Labs and their older product, the Tri-Field 100XE meter (which, again, has now been improved with their new digital model). It is just that since their older meter is so popular, a position in the marketplace that the company has well earned, and is still in the hands of tens of thousands of people including many of the people we work with, I simply want to point out to those who do use it that to accurately measure electric and radio frequency EMFs at the sensitivity that my profession considers to be healthy, it would be necessary to use other meters–including their great, new digital model (although see my comments below on radio frequencies).

For those who do have a Tri-Field 100XE meter, in order to measure magnetic fields, start on the 0-3 mG scale. You want the levels you measure to generally be 1.0 mG or less. If you read higher than 3 mG (the needle pegs to the right), you have problems and need to switch to the 0-100 mG scale to see the actual number. Move the meter closer to and then back away from a potential source to see what the safe distance is, where it gets back to 1-2 mG. Again, if a Frequency Weighted Tri-Field 100XE is elevated in the magnetic field mode, the actual magnetic field reading may actually be lower than the meter reads. However, in defense of the Tri-Field meter, I can say that if the Tri-Field 100XE meter reads below 1.0 mG, you can reliably assume you don’t have any significant magnetic fields from any source.

Less Expensive Gaussmeters

For those on a budget, there are more affordable Gaussmeters than the more expensive triple-axis Gaussmeters I mention above. The first is the Gauss Master, sold by LessEMF, Cat. #130, for only $34.95, available by clicking here.

LessEMF also sells digital single-axis Gaussmeters for under $100. This includes the Single Axis Digital Gaussmeter, Cat. #A111, for $79.95, available here. There are more on the page linked to here.

Another option is to purchase a combination meter that measures AC magnetic fields as well as radio frequency and AC electric field EMFs. There are several models that do just that.

The first is the new Tri-Field Model TF-2 combination meter. I review it in detail below. It is a remarkable and welcome improvement over their model 100XE, the best selling EMF meter in the world today. If you want to get a Tri-Field meter, this new TF-2 model is the one to get. It has several improvements that I discuss below. You can order it here.

The Cornet Improved ED88T is a Gaussmeter (magnetic field), electric field meter and RF detector. Since it only measures these three types of EMFs in a single axis, you will have to move it in different orientations to make sure you don’t miss any of these the fields, but it is an affordable way to measure them. It retails for $199.95 and is available from EMF Help Center. I have recorded a video tutorial in which I show how to assess magnetic fields (as well as radio frequency EMFs) with the predecessor to this meter, the ED78S, as well as showing how AC magnetic fields can manifest in a home. Just click here and scroll down below the Cornet meter to see the link to the video. You can order the Improved ED88T from EMF Help Center, and we will be recording new instructional videos how how to use the ED88T in the coming weeks.

I discuss and compare the Tri-Field TF-2 and Cornet ED88T below.

You can also purchase a combined Gaussmeter and electric field meter from the Gigahertz Solutions company in Germany, available at Safe Living Technologies in Ontario, Canada (519-240-8735–please mention coupon code “CHHOM”). Model ME3030B retails for $122 USD. It measures both magnetic and electric fields in a single axis, so you will have to move it in various orientations to make sure you have not missed the field, but it is accurate and easy to use. This meter does measure easily down into the 1.5 V/m level for electric fields (see below).

If you can only afford the $35 Gauss Master, then by all means purchase it, and be sure that you follow the directions that come with it carefully and learn how to orient it methodically in all directions to get the highest reading because it is a single axis Gauss meter. You will get the hang of it and it will be of assistance to you.

Also, be sure not to keep your finger on the button every time you take a reading in what they call “Mode 2,” as this is designed to allow you to get readings in tenths of a milliGauss where the scale is 0 to 1, rather than 0 to 10. This has confused many a newbie when first using this meter. The directions on the back of the meter are a bit confusing. Call me if you have any questions about how to use any of these meters.

New Combination Meters from Alpha Labs (Tri-Field Model TF-2) and Cornet (ED88T)

I have now seen and used Alpha Labs’ new digital version of their Tri-Field Meter (Model TF2). It is completely revamped, digital, and has much more sensitivity in the electric and radio frequency settings than the model 100XE, which is welcome. Plus, you have the ability to measure magnetic field levels and electric field levels in either “Weighted” or “Standard” mode, meaning you can choose which side of the issue you want to be on with a flip of a button. We would still suggest you measure in “Standard” mode, but that is now easy to do. That will give you magnetic field readings that track pretty closely to what I measured with my Gigahertz Solutions NFA1000 three-axis Gauss meter. The electric field readings tracked pretty closely with my NFA1000, getting down to levels that mean something to us (down close to 1.5 Volts/meter with breakers off in bedrooms), and the radio frequency readings were also more in line with what I measured with my Gigahertz Solutions HF59B. It gets down to a decent 100 microWatts/meter squared (0.1 milliWatts/meter squared, or mW/m2). We feel readings below 10 uW/m2 are best at night, but for the cost, this is a great improvement over the older model. I will report further as I spend more time with the new meter.

I have also used Cornet’s new ED88T. The first iteration of that meter had the addition of an electric field setting, which only went down to 0.5-0.8 Volts/meter in my experience, not low enough for us (we want electric field readings to be 1.5 V/m or less in sleeping areas). However, Cornet now has an improved version of the ED88T, the “Improved Tri-Mode (Hi/Low Frequency) Meter”. I have not yet used that model but will do so in the coming weeks and will report back at that time. I already know the Cornet meters, starting with the ED78S, have a very accurate RF meter for the price, getting down to 1 microWatt/meter squared (uW/m2). That is also true for the first versions of the ED88T I have used.

When considering the Tri-Field TF-2 or the Cornet ED88T for taking more sensitive RF readings in a combination meter, choose the new Cornet ED88T. Also, I anticipate the sound that you will hear with the Improved ED88T will help you differentiate the actual RF sources in the room or coming in from outside. I have had that capability with every Gigahertz Solutions RF detector I have owned, and it is invaluable at helping me determine what RF sources are impacting the environment I am evaluating for my client. The Tri-Field TF-2 does also have sound, but it is only an audible measure of the strength of the signal (as helpful as that is), not an audible representation of the RF signal sources themselves, as with the Gigahertz Solutions and other brands of RF meter. I am waiting to see if the Improved Cornet ED88T has that capability and how good the sound is, as that is something particularly helpful in determining RF sources.

Regarding measuring AC magnetic field EMFs (the “M” of the EMF), on the other hand, that mode in the Cornet ED88T is single axis, not triple axis, as the magnetic field mode is in the new Tri-Field Model TF-2 (and the older 100XE models). As a 3-axis Gauss meter, you essentially get the same reading in any orientation. So, if you want an easier meter to read accurate magnetic field readings and not miss the true value because you don’t want to have to move the meter in all three axes, choose the Tri-Field TF-2.

Also, the Tri-Field TF-2 appears to measure electric field readings somewhat lower than the Cornet ED88T, getting down closer to 1 V/m. This is very important to us when measuring sleeping areas. (Of course, my all time favorite for accurately measuring AC electric field EMFs where you sleep is still the body voltage meter, available from LessEMF by clicking here and from Safe Living Technologies by clicking here.)

Overall, the Tri-Field TF-2 is a great new combination meter for the price from the maker of the most commonly used EMF meter in the world. Good work, Alpha Labs.

Cornet continues to do a great job, as well, improving their already great combination ED88T meter.
