The Best Electromagnetic Field (EMF) Detectors for 2020

How Does an EMF Detector Work and What Are The Applications?

An EMF detector measures magnetic fields, electric fields and RF radiation through sensors. An EMF detector that measures these quantities will have three sensors, one for each of the type of field being measured. The accuracy of the sensors depends on their sensitivity: the higher the sensitivity the higher will be the accuracy of the measurement.

EMF meters have a wide variety of applications. They can measure

RF radiation and the amount of RF power emitted by mobile phones, cell phone towers, WiFi routers and Bluetooth devices.
Magnetic fields around AC power lines and transformers.
Electric fields around electrical and electronic appliances such as refrigerators and laptops.

Best EMF Meter

Trifield – EMF Meter Model TF2

After extensively researching EMF detectors, we think the Trifield® – EMF Meter Model TF2  is the best EMF meter available on the market today. This instrument provides fast and accurate measurements for magnetic and electric fields and for radio frequency (RF) radiation. The meter also supports a special frequency weighted mode: this mode allows accurate measurements of currents inside the human body which are produced by magnetic / electric fields and by RF radiation.

Trifield -EMF Meter Model TF2

The EMF Meter Model TF2  is easy to use and comes with a large LCD display with adjustable backlight. The unit is powered by a 9 Volt alkaline battery which gives up to 20 hours of run time. The EMF Meter Model TF2 offers an economical package which can be used for accurately measuring the three main types of electromagnetic pollution. 

The Trifield® – EMF Meter Model TF2  measures all three types of electromagnetic fields of interest: AC magnetic fields, AC electric fields, and RF radiation. In AC magnetic mode it covers 40 Hz to 100 kHz over 0.1 to 100 milligauss range. The meter uses a 3-axis magnetic sensor which enables accurate measurements regardless of the direction the meter is being pointed at. In AC electric mode it covers 40 Hz to 100 kHz over 1 to 1000 V/m range. In RF mode it covers 20 MHz to 6 GHz in 0.001 to 19.999 mW/m 2 range. The meter comes with an audio output to help locate EMF radiation sources. However the field strength displayed on the meter LCD will still need to be used for actual EMF radiation levels. Another plus is the weighted mode which is designed to enable measurement of effects of EMF radiation on the human body. 

Flaws but not deal breakers

Both the audio and backlight buttons can be accessed only after removing the battery cover which can be a bit frustrating. However keeping the audio and backlight buttons off the front of the meter does help to give it a cleaner and simpler look. 
Some users may find the weighted mode a bit confusing. The basic recommendation is to use...
