The 10 Best EMF Meters Review:

With many options available, finding the ideal EMF meter isn’t an easy task. There’s no need to worry, though. We’ve simplified the research by picking the top ten tools that delivered the best results. Here, we’ll introduce them to you.

1. Trifield – EMF Meter Model TF2

Trifield Electric Field
  • Detects all three types of EMF pollution: AC magnetic, AC electric, and RF/microwave
  • Displays signal level, peak level, and a fast indicator bar (for pulse monitoring)
  • AC magnetic, AC electric, RF/Microwave (measures total RF signal but NOT frequency)
  • AC fields: can measure standard measurements or weighted (proportional to current induced in the human body)
  • Made in USA; 1-Year Manufacturer Warranty

We’re starting with an EMF device that detects all three types of EMF: AC magnetic, AC electric, and finally, RF/microwave. The instrument includes an indicator bar that quickly indicates hot spots, warning users about the radiation source proximity.

Even though the device is a bit bulky, figuring out how it works is not hard. In fact, users can turn the knob to the type of field they want to measure, and the meter will be ready to pick up the EMF. Then, the large LCD included at the top guarantees you get accurate, detailed readings.

Furthermore, the device also puts up a good performance as the best EMF RF meter. The RF mode is sensitive enough to pick up EMFs from mobile phones, Wi-Fi, and more. All the types of readings available make this product a versatile tool for amateurs and advanced users.

The biggest downside of this unit is noticeable when you’re trying to access the audio features. To do that, you’d have to remove the battery cover, which is not ideal. Over time, though, you get used to how the device works, which allows you to adjust faster.


  • High accuracy while measuring AC magnetic fields, electric fields, and RF
  • Features a large display that is easy to read
  • Simple layout with just a knob makes the device easy to use for everyone
  • The Peak Hold is an improvement from previous models that didn’t have it

Buying Guide: What to Consider When Choosing EMF Meter

After reading our EMF meters review section, let’s briefly talk about the main features that customers must consider before finally picking a device.

EMF Meter Capacities

a) Detection Capacities

Before picking a device, you must figure out what kind of radiation you want the device to detect. While some EMF meters are capable of picking AC magnetic fields, electric fields, and RF, not all of them have the same capacity.

Do you want to measure magnetic fields from appliances or radio frequencies? Knowing what you want to do beforehand will allow you to narrow down the list of options to only a few devices worth considering.

b) Sensitivity

Depending on what you want to test, more or less sensitivity could play a huge role in the device’s readings. Of course, super-high sensitivity could also be a disadvantage because it may make it harder to identify the source emanating the radiation if there are other appliances nearby.

Naturally, you don’t want a device with ultra-low sensitivity either. Detecting the EMFs would be much harder in this case.

What you’ll need for your activities is simple: a device with adjustable sensitivity. There are several included in our list, meaning you get to buy a tool that actually adapts to your needs.

c) Interface

The EMF meter is a tool that doesn’t take much thought to figure out. You turn it on, point the sensor at the appliance you want to test, and the device detects radiation if there’s any. It sounds so simple, and yet, many manufacturers don’t get it right.

While purchasing one of these devices, make sure the user interface doesn’t make things harder for you. Ideally, you want a backlit screen with enough indicators, measurement settings, and an analog/digital display.

The button placement is another feature customers have to consider. Although not many, detectors with buttons for on/off, safe value, temperature adjustment, and changing modes will make your tasks much easier.

d) Notifications

A device featuring lights or warning sounds will keep users informed about the proximity to the radiation source. Now, even though most EMF detectors have this type of notification, not all devices use them correctly.

In many cases, you’ll find detectors that go crazy over nothing, provide false readings, or just can’t locate the source.

Pay special attention to devices that offer options to either disable or adjust the sound alarm, as it may come in handy for specific situations.

e) Portability

Testing electrical appliances may take us to different rooms in the house, which is why a compact EMF meter would come in handy. You can keep it in your pocket, ready to use as soon as you encounter a potential source of radiation.
