RF EMF Meter HF-B8G High Frequency 10Mhz-8Ghz. Measures Wide-Range Electromagnetic Radiation from Cell Towers-Smart Meters-Wi-Fi-Cordless and Cell Phones-3G-4G-LTE & 5G Networks

Good equipment if you have high power lines nearby.

Easy to use and set up.

Was able to tell if there was a difference in the interferences I was experiencing based on what technology was on around.

Everywhere you place this, it detects 0 almost, meaning its sensitivity is ultra-low versus other amazon meters, and if you use some cell phones it will say something like 90 mw/m2 or something, it's absolute trash. Get a GQ-EMF390 or the Safe Sound meter.This made-in-Taiwan piece of crap only has a nice box to go with it, accuracy is nonexistent.

Very accurate but doesn’t pick up 5g. Sometimes the buttons don’t work properly

I recieved the instrument ahead of scheduled delivery date - nice. Carrying case and snug fit instrument lining will be great protection, allowing for more years of service. Ruggedly built instrument - Feels comfortable in handling. Tested once so far, but need more time in field and indoors using various features.

I have a huge problem - a neighbor maliciously propagating emfs in my direction. I have purchased three meters - the MG-300, AF-3500 and HF-B8G.So far all of the meters have revealed very high levels of low and high frequencies. I'm in the learning process of using the x,y,z axis function to generally locate the source.I have been living with emf levels as high as 18,000 mV/m and low frequency levels of 76.00 mGs.I'm on my own here and could use some expert advice. I'm slowly proceeding on a learning curve.

I appreciated how this came with a calibration certificate. Also to note I gave an accuracy of 4 starts because the readings become unreliable and appear to increase as the battery goes below 50 percent charge. With a fully charged battery its very repeatable in its measurements.
