Should I Buy an EMF Test Meter?
by James Finn ©2022
In my opinion, everyone should own an AC Gaussmeter and an RF meter. With our virtual remote EMF testing program, you can learn how to use these non-invasive consumer-grade meters to safely test your home or office space and begin to take control of your EMF environment. (Note: These meters will only test a part of the EMF spectrum. For a thorough assessment, you need to call a pro.)
An AC Gaussmeter measures the Extremely Low Frequencies (60 Hertz) magnetic flux from power transmission lines, substations, electrical distribution lines, transformers, appliances, etc.
An RF Meter measures microwave power densities from nearby cell tower transmitters, smart meters, WiFi, NEST, Alexa, Bluetooth, security systems, cellphones, printers, etc.

“Elexana Best Choice” Amateur RF Meter
The Safe and Sound Classic
For those who do not do EMF Testing professionally, using amateur meters with pro sensors is the way to go. We have been checking out the Classic’s younger sister, the Safe and Sound Pro, and have been impressed. Because this Classic incorporates the same pro sensors with just an ON/OFF switch, it can easily fit in your front pants pocket, and the price point is $171 with your Elexana-SLT discount code; this is our Choice RF Meter. (Prices are subject to change. Please, include shipping.)
We have recommended this meter to all roof workers, those with EMF sensitivity, and more. The reports back are that they love its ease of use, size, comfort, and safety it provides.

This is a nice meter. I love its easy use, the audio demodulation, the clear function, the running average, and its portability.
“Elexana’s Best Choice for Virtual Remote RF Testing”
Gigahertz Solutions 35C
We love the 35C for it’s price point and the log directional antenna. It’s perfect for our virtual testing program, easy to use, and gets the job done.

“Elexana’s Best Choice” Amateur Gaussmeter
Alpha Labs UHS2 Gaussmeter
Our choice is a professional Gaussmeter that can also be NIST certified. We own three of these in addition to our 5-Gigahertz Solutions NFA 1000’s. The Alpha Labs UHS2 makes for a great backup meter for any pro. We like its ease of use and that it has both an omnidirectional and single-axis capability. You can also switch back and forth between ELF and VLF frequency ranges easily.

This AC Milligauss Meter Model UHS2 measures an AC magnetic field in a frequency range of 13 Hz to 75 kHz (75,000 Hz). The frequencies include most ELF (frequencies below 1 kHz) and VLF (above 1 kHz) magnetic fields. The meter measures the true 3-axis magnitude of the AC field. Two more specialized measurements can also be performed: 3-axis VLF-only (1kHz – 75 kHz) to measure the strength of higher-frequency fields and 1-axis full bandwidth (13 Hz – 75 kHz) to determine the principal direction of the AC magnetic field.
Most measurements will be performed with the knob turned to 3-Axis ELF+VLF. This setting measures the true magnitude of the magnetic field at the most comprehensive range of frequencies (ELF + VLF).
Features:
NIST Traceable
Hard Shell Zipper Case
SPECIFICATIONS: AC Milligauss Meter UHS2
Frequency Range:13 Hz – 75 kHz
Maximum Range:1999.99 mG
Resolution:0.01 mG
Accuracy:±3% from 45 Hz to 5 kHz, ±7% below 45 Hz and above 5 kHz
Battery:9 volt alkaline (~20-hour life) / “Low Battery” indicator
Note: For amateurs, we also like the Alpha Labs TF-2 Digital EMF Meter for just the AC Magnetic aspect of the meter. We feel that Alpha Labs UHS2's flexibility, for less than $100, makes it a better choice.
