Since you are reading this article about EMF detectors and meters I assume you already know that we live in a world where we are constantly being exposed to harmful electromagnetic fields (EMFs).

Unfortunately in our modern world it isn’t possible to get away from the radiation that is all around it. Your TV, cell phone, tablet, smart watch, radio, laptop and all the other electric devices that surround you all emit harmful EMFs. Not to mention the radiation that wifi, Bluetooth and electricity all produce.

One of the first steps you can take to protect your family is to invest in a quality EMF meter or detector.

Why An EMF Meter?

A magnetic field meter will help you reduce the levels of radiation in your home by locating exactly what is putting out the highest levels of radiation.

Best EMF Meters

With so many detectors and meters on the market it can be overwhelming trying to decide what one to buy.

That’s exactly why I have spent hours researching and testing multiple meters to find the best ones. I have put together this list of the top 7 best EMF meters and detectors.

1. TriField EMF Meter TF2

TriField EMF Meter Model TF2The TF2 from TriField is one of the best selling meters on the market and for good reason.

This professional grade meter can detect three kinds of EMF radiation: AC magnetic, AC electric, and RF/microwave. It’s easy to use and it’s a great option for anyone concerned about RF in addition to EMF radiation.

The TriField’s unit detects an impressive range of frequencies for each type of radiation, allowing you to better home in on which devices in your home are putting your family at the most risk.

One of my favorite features is the fast indicator bar that quickly show the hots spots. You can also adjust the brightness of the screen which can come in handy. Click here to check it out.

2. Advanced GQ EMF-390 Meter

Advanced GQ EMF-390 detectorThe GQ EMF-390 digital meter will allow you to easily and quickly detect EMF, ELF, EF, and RF radiation from all electronic devices both indoors and outdoors. Click here to check it out.

It detects a huge frequency range (EMF 0- 500mG and RF up to 10GHz) and has multiple sensors for highest accuracy and maximum range measurement.

This meter can identify and recognize radiation sources including power lines, cell phones, WIFI, cell towers, microwave, smart meter etc. With a built in audio and visual alarm and all-in-one display to see readings from all sensors at the same time.

Here are some of the features:

  • High sensitivity sensors
  • Ultra-fast readings
  • Advanced functions
  • Portable and convenient
  • Built-in memory for data logging
  • Safety Suggestions to understand your readings immediately

This meter has one of the best sets of capabilities in its class. Click here to find the best price.

3. Latnex MG-300 LF

Latnex MG 300 LF emf meterThe Latnex’s MG 300 has many of the standard features you’d expect. With a detectable frequency range of 30Hz to 300 Hz, this meter can detect frequencies from high power lines, air conditioning units, refrigerators, appliances, computer monitors, audio and video devices and more.

This meter is commonly used for EMF home inspections, measures 130(L)*56(W)*38(H)mm, weighs about 170g and is reasonably priced.

Here are some of the features I like:

  • Easy to use
  • Single axis sensor
  • Data/max hold function
  • Long battery life (approx 100 hours)
  • Measure in μT and mG
  • Comes with a black protection boot and carrying case

Click here to find the best price on the LATNEX MG-300.

If you are looking to measure electrical fields with high frequencies RF waves I recommend you check out the LATNEX AF-3500 or AF-5000 that measures high frequencies too.

4. Latnex HF-B3G Meter

Latnex HF B3G emf meterLatnex earns a second spot on this list with the HF-B3G. The HF-B3G meter is a solid, high end detector worthy of consideration.

The LATNEX HF-B3G is ideal for anyone looking to measure radiation from cell phone towers, smart meters, microwaves, Bluetooth, cell phones, WIFI modems and more.

Here are some of the features:

  • Beginner and advanced operation modes
  • Alarm/buzzer function
  • Tri-axial sensors
  • Data memory storage
  • Battery life approximately 15 hours
  • Digital clock

Capable of detecting frequencies in the 50MHz to 3.5GHz range, this device is ideal for detecting frequencies from a wide variety of devices, including wireless bugs and spy cameras. Click here to learn more.

5. Meterk Meter

Meterk EMF DetectorThe Meterk Meter is ideal for anyone on a budget looking to measure low frequency home appliances such as refrigerators, fans, cell phones, televisions, induction cookers, rice cookers, computers and laptops, electrical wires, low frequency home appliances and more.

One cool feature about I like about this meter is that it measures the magnetic field and temperature radiation at the same time.

Here are some other features:

  • Sound light alarm (automatic when results exceed safe value)
  • Data hold
  • Low battery indicator
  • Can set to read in Celsius or Farenheit
  • Auto power off
  • Backlight LCD display

This meter is easy to operate with one hand measuring at only 1.97 inches wide and 1.06 inches thick. Click here to find the best price on the Meterk EMF meter.

6. KKMoon EMF Detector

kkmoon electromagnetic field radiation meterIf you’re on a tight budget, it can be difficult to justify purchasing one. You want to keep your family safe, but the high-end detectors out there are an expensive initial investment.

The KKmoon meter is very similar to the Meterek detector mentioned above.

This meter can detect frequencies electric from 0 to 2000mG and magnetic from 0 to 200μ, which is an impressive range for a budget detector.

Here are some of the features:

  • Large and clear LCD display
  • Easy one hand operation
  • Sound and light alarm
  • Date hold and maximum measurement
  • Tests both temperature and magnetic field radiation.

The KKmoon is a quality detector suitable for anyone looking to buy a meter on a budget. Click here to check it out.

Measuring EMF Radiation

The readout on the meter starts at a small green light and jumps to a fourth or fifth bright red light. There’s also a digital readout screen. On the digital readout screen, you will see numbers in .1 increments. The lower the number, the safer the electronic device. The ideal is to have a device read exceptionally low or not read at all.

If you don’t have other protective measures in place like a Wi Fi router guard, it is certain that your WiFi router will have readouts on the EMF meter. Computer, laptops, cellphones, smart TVs etc will all have readouts on the detector. Really high readouts are usually anything above 1.0, and anything above 1.5-2.0 is considered dangerous to your health.

Most objects will have a readout of .4-1.0. That is common and it is considered safe, although you may still want to reduce those amounts anyway. Some people are especially sensitive to readouts that fall in the safe zone, and have been negatively affected.

A good EMF detector is a useful tool to have when it comes to protecting your family against EMF radiation. No matter what your budget, there is an meter out there for you. I hope you have found my list of the 7 best emf detectors helpful.


EMFs are literally everywhere and virtually unavoidable. Many experts have done research that has linked even low levels of radiation to harmful health consequences. You can’t get away from being exposed to EMFs completely but there are some reasonable things you can do to minimize the risks associated with its exposure.

Luckily there are all kinds of products on the market that will reduce your exposure to EMFs everything from cell phone cases blockers, laptop shields etc etc. which I will discuss in more detail below. You can use your meter to see if the levels have been reduced.


I began learning about EMF out of fear and safety for my kids, wife and myself. This set me on a passionate (aka obsessive) path of research, which has led to this site in hopes of helping you and others like us protect yourself and your family the way I have.
