Review on EMF Meter, Hand-held Electromagnetic Radiation Tester with LCD Display - Ideal for Home EMF Inspections, Office Use, Outdoor Activities, and Ghost Hunting by Kenny Beyer

I ended up returning it. That's very inaccurate. I bought another more expensive device and compared it. While this device shows 0.00 µs, the other device has a small value, e.g. 0.14 µs. And while this device shows 1.0+ ut, the other device shows 0.23 ut, for example. It seemed very inconsistent and I wouldn't rely on it for accurate measurements.
