7 Best EMF Meters and Detectors of 2021
The price is extremely reasonable, and you honestly will love how accurate and simple to operate this device is. It is extremely accurate, simple to use, and preferred by professionals.
However it does have its downsides, for example, it only reads RF radiation, and is not designed to read electric field or magnetic field radiation. There is a reason that you will see the Acoustimeter AM in the hands of so many professionals, it is extremely accurate and simple to use. Things I Love About The Acoustimeter AM Sensitivity — To start with, the Acoustimeter is one of the most sensitive RF meters on the market, capable of reading even the smallest amounts, of the lowest radio frequencies and displaying them.
Not only that, but it also has fantastic directional sensitivity. This will allow you to easily locate the direction that the largest RF radiation sources are coming from by simply moving your Acoustimeter in a circle and watching the display to see peak readings. I have a great guide on how to see a map of every cell tower near your home. Frequency Range — The next thing I really like about the Acoustimeter is the enormous frequency range that it is able to measure.
For example, the Trifield TF2 is capable of reading up to 6Ghz which for now is probably plenty whereas the Acoustimeter can read all the way up to 8Ghz, giving you a wider range than you are able to measure. Ease Of Use — Next, the Acoustimeter is really simple to use. There is a simple display at the top, as well as two rows of LED lights below. When using the meter, I personally like to plug in a pair of headphones into the audio jack with or without the headphones and use the audio to help me locate sources of RF radiation.
If you take a look at the small screen to the right, you can see what will typically be displayed. Here is how you would read this screen: The 5. The 2. Overall I find the Acoustimeter really easy to use, especially once you get a used to it. At more than double the price of the TF2 at the time of this writing , you certainly want to make sure this is the device for you before purchasing.
Just understand that you are paying for the accuracy and quality of the machine, not for bloated features. Size — Next, the device is relatively bulky. Limitation — It is unfortunate that the Acoustimeter only measures RF radiation, and not magnetic or electric. Frequency Readings — One of the reasons that many people purchase the Cornet ED88T is that it not only gives you a reading of the RF radiation in terms of signal strength like the Acoustimeter did, but will also show you the actual frequency that it is picking up in a range of Mhz to 2.
It has a similar range of MHz — 8GHz and appears to be extremely accurate. Sound Feature — I like that the Cornet does feature a sound output for Radio Frequency radiation readings, which I personally find extremely helpful when measuring radiation in a space like a home or an office.
Reading History — This is one of my absolute favorite features of the Cornet. This can be especially helpful for getting readings from things that have a tendency to pulsate, such as Smart Meters.
Smart meters usually have extremely high spikes or radiation when transmitting information, however, this occurs very quickly and it can be hard to get an accurate reading. With the Histogram feature, this is a piece of cake and you can easily look back at the reading. There are only a few buttons, which you would think would be a good thing, but it is not clear what they do, and I found that when first using the device I was stumbling around a bit.
In contrast, I found the Trifield TF2 to be almost impossible to not use correctly, as you simply turn the large dial on the front to what you want to measure, and off you go. I also felt like the user manual that comes with the Cornet ED88T was not all that helpful in showing you how to properly navigate the device. All of the other units of measurement displays can be changed in the settings luckily. It does have some unique functionality, like reading the frequency range of Radio Frequency.
It can also store that data with its built-in flash memory. You can display all that data later and download it to your computer using free software. One of the coolest parts of the GQ meter is that it can actually display all three readings at one.
You can literally get magnetic field, electric field, and radiofrequency readings displayed all at the same time. You can of course also turn it to a more classic mode for each type of reading which will just display more information specific to that type of EMF.
If you absolutely love data, then this might be the EMF meter for you. It can do really cool things like track multiple RF radiation sources at the same time. If you look at the image to the right you can see that the meter is displaying readings from a nearby microwave oven as well as the ambient RF radiation coming from a local WiFi router. The Latnex is a great radio frequency meter and is sort of a budget version of the Acoustimeter.
Offering only radiofrequency radiation detection, the Latnex does not offer a full range of detection but does some great quality for a reasonable price. Latnex EMF Meter Pros Triple-Axis — The Latnex does have a triple-axis radio frequency detector the ball on the top of the device which allows you to get accurate readings regardless of the orientation of the device.
Great Manual — The Latnex comes with a very detailed user manual see that here that really comes in handy. I find the manual to be even more thorough than the manuals that come with some of the higher quality meters. Easy To Use — With a simple display and 7 nicely labeled buttons, the Latnex is a breeze to operate. Like the Acoustimeter, this is how the device is designed, but it is certainly nice when the meter measure all types of Radiation like the Cornet or the Trifield TF2.
Quality — Latnex, although they make a variety of EMF meters including ones that measure magnetic field radiation, it has not been around as long as some of the other companies. This makes me doubt the reliability a little bit since it has not stood the test of time. Final Thoughts The Latnex is a great radio frequency meter with great reviews. That is just my honest opinion and suggestion. This has become one of the most popular inexpensive EMF meters in , and for pretty good reason.
Like most inexpensive EMF meters, this one is not able to read radiofrequency radiation, and only reads magnetic field and electric field. However, it also takes ambient temperature readings. One of my favorite features other then the flashlight is the display light on the antenna, which actually acts as an alarm. Overall, for the price, this is a fantastic value and a great introductory EMF meter for just about anyone.
Next, I want to take a look at the Meterk, which is on this list primarily because it is, in my opinion, the best budget-friendly EMF meter on the market. Now there is a reason for this, the Meterk does not have nearly the features or build quality of these other meters, however for the price, I think it is the best on the market. This allows you to get a feeling for how these devices work, the information they can provide you, how that information can benefit you, etc.
Later down the road after you realize how important these devices are, you can opt for a bit higher quality, more feature-rich device like the Trifield or the Cornet. There are a few reasons for this, with the largest being the fact that it is developed and manufactured in China, so they are able to produce it at a very low cost. It also has a nice bright green screen that turns red when readings get high.
Cons of the Meterk Meter No RF Reading — The biggest downfall of the Meterk is that it only reads magnetic and electric field radiation, not radiofrequency radiation. However, this does mean that the Meterk could be a really good compliment to the Acoustimeter, which reads RF, but not electric or magnetic radiation. Not Tri-Axis — Whereas many of the EMF meters on this list have tri-axis capability meaning they will get an accurate reading regardless of orientation , the Meterk requires that the sensor located on the right-hand side is pointed towards the source of the radiation to obtain an accurate reading.
Quality — I cannot say that the Meterk is made of the highest quality. I have owned it for quite a while without issue, but it is not from a long-standing reputable company like Trifield, Acoustimeter, or Cornet. This also means that the accuracy is likely to be less reliable than these higher quality meters.
Although it lacks the quality and features of the other meters on this list, it is a great choice for your first EMF meter. You can pick up the Meterk on Amazon. With a quality EMF meter, not only can you gain a thorough understanding of the type of EMF radiation in your home, but also the amount.
These guides offer tons of solutions to lower your exposure, but without an EMF meter, it is difficult to get a real understanding of how much radiation exposure you actually reduced.
You can use the meter to detect large exposures of magnetic field, electric field, or radiofrequency radiation in your home, apply a solution, and test how much the solution reduced the risk. For example, SafeSleeve see my review has a line of cases for cell phones, tablets, and laptops. These are great examples of products that you can test with your EMF meter. Simply start by making a call on your cellphone and measuring the radiation levels. Then, put your phone inside the case, and measure the radiation levels again to see how much radiation it will be protecting you from.
What About Dirty Electricity Meters? Dirty Electricity is an entirely different, although equally important, subject. Dirty electricity is essentially leftover electricity that was not able to be utilized because modern electronics alter the electricity they receive from the wiring in your home. This electricity then sits in your wiring, emitting large amounts of EMF radiation.
9 Best EMF Meters and Detectors – My Top Picks!
That also means the ubiquitous nature of EMF is tricky to measure without a highly sensitive instrument. Because there is no such thing as one meter that can fill every need. Picking the right meter requires you fill in a couple of blanks. The first thing you want to ask? What it is you wish to measure. Types of Radiation Detected Are you trying to measure magnetic fields, like may be coming from power lines, appliances, and cars?
Do you want to measure electric fields from like lighting, extension cords, and monitors? Are you trying to measure radio waves emanating from cell towers, microwaves, or Wi-Fi connections?
How about dirty electricity in wiring, or body voltage in appliances? Different EMF meters and detectors are made for different purposes.
Sensor Accuracy and Sensitivity How sensitive and accurate you need your meter to be? Can you only detect strong signals? Is the device capable of getting within a couple of Hz in its measurements, or are you looking at ballpark figures? But suffice to say, more accuracy and more sensitivity will increase the cost of the instrument you end up selecting. User Interface How complicated is the instrument? How difficult is it to take a reading, and then use that information in a practical way?
Can the data you collect be ported off the device in some way? Do you get the readout in an analogue display or digital display? Whether or not the instrument is sufficiently portable can make-or-break a selection every bit as much as its actual features. Sturdiness also relates to portability. Its peak hold capabilities can help you capture even the fastest EMF pulses. With its sensitivity is down to about 0. The topside has a display that measure about 2. Better than nothing, I suppose.
That makes it much easier on the eyes. It also makes it much easier to read the 1-axis data readings, and helps the display keep up with the relatively fast indicator bar. The leftmost setting is the off-setting. The color coding on the dial is fantastic because having three separate colors makes this pretty easy and intuitive to use. With the backlight turned off, you can get about 20 hours of power out of the battery. Originally developed in Seattle, this instrument is a redesign of classic EMF meters, now intended to be convenient above all other things.
Multi-sensor function is essential to being able to deliver an accurate picture of the electromagnetic field. The sky is the limit, and in a literal sense. Though it can still fit in your hand, it would be a mild exaggeration to call this a handheld device. The front face of the device has four simple operation buttons. Unfortunately, only one of them is labeled, which is the power button. The display is fairly small.
It measures roughly 1. Just about the worst thing you can say about this meter is that the display looks like a graphing calculator. Pretty much exactly what you want for showing different types of data. The graphic function provides real-time data readings, positioned alongside a graph of the past seconds of data collection. The browser can also visualize RF radiation across your screen. For instance, distinguishing between overlapping Wi-Fi and microwave signals. How does your data get saved?
The built-in flash memory has formidable support for data logging, which includes timestamps for all the data collected. History can be downloaded after the device is linked up with a PC. You can get the data sync software from their website. As you move between various windows on the display, you can write down data for comparison, but actually tracking it in real time is a little more challenging.
The side of the unit has a simple switch and control wheel, which can be used to navigate the AM and its control settings. The whole thing is quite intuitive. Perhaps more importantly, this meter has fantastic sensitivity. Even when signals are fairly weak, the Acoustimeter AM is pretty good at picking them up. It looks a bit like an old calculator with a large speaker on the back.
It even has a battery port where a calculator might have one. You need to insert a pair of AA batteries to power the device. By only using the display, a couple of LEDs can inform you all about the strength of various readings.
Data captured includes both the peak and average measurements, and always within a reasonable range of approximation. Other Considerations On the backside, there are instructions on the meaning of the various readings you can take with this meter. If an inexperienced person is expected to take measurements, the AM allows that person to be successful with minimal training. The AM was made in the United Kingdom.
It includes a nylon sleeve, plastic carrying case, two alkaline AA batteries, a user manual, and a two-year warranty. But looks can be deceiving. The analogue interface is intuitive, even if it does feel a bit dated.
Given its low cost and wide abilities to measure and detect EMF, this sensor is worth picking up. Its portability is fantastic, especially with the built-in lanyard strap.
Ease of use is pretty good, mostly because you only use four buttons to operate the device. Sadly, there are a few things to dislike as well. The screen is a bit cramped. The interface is basically idiot proof. And there are instructions on the back of the unit. That makes this a great meter for educational purposes, and for inexperienced users. Trying to suss-out a weaker signal? The AM is probably your best bet. Was this helpful? Please consider sharing:.
Ultimate Guide to the Best EMF Meters & Detectors
If it can cover all the frequencies from 0 to GHz, then it is good. In terms of 5G; that is a hot issue currently, if your EMF meter can cover up to 3. This is important to allow you to measure any type of radiation generated by the electromagnetic wave. You have to approach these 3 radiations to get a comprehensive reading.
Some EMF meters only cover two readings: magnetic field and electric field but they claim cover 3 readings including the RF radiofrequency reading. You have to carefully choose them. The best way to avoid this event is to take a look at the frequency response the meter can cover.
Best EMF Meter Reviews
If it cannot cover more than 10 MHz, simply it is not able to measure RF radiation. Accuracy In terms of accuracy, this part actually covers things such as a 3-axis sensor, NIST traceability, and sensitivity.
This is meant to catch the magnetic field orientation. When a device has a single axis sensor, it may take the wrong orientation of the magnetic field. To get a proper measurement, a single axis sensor must be rotated to get the highest possible reading as the correct reading.
Keep in mind that this must not from NIST. Generally speaking, if you want the most accurate readings, then it pays to get a more expensive item. These ones come with three-dimensional readings that provide you with more in-depth results.
Typically, the electromagnetic radiation is signalled via a number. This tells you the frequency of the radiation, so you can see how much is present. High numbers mean a high level of radiation, and low numbers equate to lower levels. You can change the direction you aim it in to see how the frequency differs from area to area.
Why do you need an EMF Meter? So, EMF detectors help you find electromagnetic field radiation — but, why is this important? This meter measures both the Peak and the Average at the same time.
I really like that feature as well. With this meter you can see both what the highest spikes are, as well as what each device emits on an average. I am excited to get one of these meters. Its price. It is the most expensive of the meters I am reviewing. But other than that everything else about this meter is positive. Like I always do I said sure, as long as they send me one and as long as thy understand despite them sending it for free, I am going to give my honest opinion on it.
They said sure, and sent me the meter. Below is that video that I did reviewing it: I had a mask on the first few seconds of the video as a joke. As you can hear in the above video it seems like a good quality meter. It reads digitally but seem to pick up the same electric fields and magnetic fields as the Tri-Field does and the readings were comparabel.
So if all you are wanting to measure is electric fields and magnetic fields, this is a great quality, inexpensive option. However in my opinion since dirty electricity and RF Radiation are so much more powerful, they are a much bigger priority. This is my favorite meter for measuring Radio Frequency RF Radiation, mostly because I have used it the most and am used to it.
It can be set to give the Peak Measurement reading which means the highest reading received during each second or so. RF Radiation is powerful enough radiation that you can pick it up from a room or several rooms away in some cases.
There is much to be said about going through a home and being able to point the meter around the room. When the meter starts freaking out you know the device you are pointing it at is the culprit. That may be why I like that feature. Some devices I thought would give off a ton of RF Radiation barely gave off any, and yet the device in the same room was emitting a ton.
With a meter like the TriField TF2 Meter above you just have to turn off devices one at a time, or move the meter closer to each device, so you know which device you are picking up the radiation from with the meter.
The Best Radio Frequency Detectors to Buy Right Now
It is not that big of a deal though. Electric and Magnetic fields generally do not travel as far and are not as powerful of a signal so not having a directional meter is actually easier like the TriField TF2 Meter. With low powered EMF Radiation you have to hold the meter closer to the device anyway. I hope my logic there made sense to everyone. You will see exactly how this meter is used and how it works in this short video.
It is also worth watching. I know people promoting other meters for RF Radiation extol the virtues of non-directional sensors. Having used both, for RF Radiation directional is better and easier in my opinion. But you can be effective using non directional meters. It is mostly just a preference I suppose. It is a tank. It is very well built. I have had mine for over 4 years and use it all the time and it is still running strong. I have not even ever has so much as a battery issue.
Highly Accurate: I have tested this meter along side other meters that measure RF Radiation and this one is just consistently accurate. Most others are too. But if I ever doubt the reading on another meter I double check it with this one. Peak Measurement Setting: The whole point of using a meter to measure RF Radiation is to know how high the bursts of radiation read. The easiest way to see that is to have the meter set on its Peak setting.
Very important. As much as I rave about this meter, and I do love it, it does have two very significant cons. It only measures RF Radiation. It does not measure Electric or Magnetic Fields. And 2. These are the only reasons that this meter does not rank higher on my list. So this is the meter I use by far more than any other, so I am glad I have it.
It makes RF Radiation reading so much more convenient. This is a meter I am very impressed with as well. This is also one I do not own yet, but I will be picking one up. You will understand why as I go through this review. I have read and watched numerous reviews of this meter and compared it to numerous reviews of the other ones and I will tell you what I like about this. First of all this meter measures 3 types of EMF or electromagnetic fields or radiation.
So again owning this meter it is like owning two meters in one. In this video below the man in the video demonstrates using this meter to test the radiation coming out of his microwave.
Microwave radiation is RF Radiation just like a cellphone, Bluetooth or a wireless router. Watching this video will give you a good feel for this meter and how it works. Once I get one of these meters myself I will update this article and do a video myself as well. At the beginning of this section I put a link for you that will take you directly to where you can buy this meter on Amazon. Well Constructed: In all of the reviews I have read and watched on this meter quite a few of them mention that it is built well or that it holds up for a long time.
Headphone Port: Since this meter also puts of audio noises that correspond to the reading on the meter, they put a head phone jack on this model so that you can listen to the noises privately if you choose to. That way I guess your not bugging people if you are testing things around a lot of other people. Directional Meter: This meter does pick up the RF Radiation in a directional manner so you can tell which direction the RF Radiation is coming from when you are testing.
I like this feature on a meter but I know some other people prefer non-directional meters. Fairly Simple To Use: This meter is fairly simple to use.
It has more buttons and is a bit more complicated than some of the other ones, but not too complicated. I think everyone can run this one quite easily without any problem. But like I said not enough that I personally think it should be a deterrent for anyone.
It still is pretty simple to operate. Okay this is a meter that many people recommend, mainly because it is so inexpensive. This meter is pretty complicated to run for a new person. It is more complicated than the other meters. There are lots of videos that on YouTube that show how to run the older model, and I am sure videos will be coming out about the newer one.
