LATNEX AF-5000 5G EMF Meter RF Detector Tester and Reader with Calibration Certificate - Tests and Measures RF and Microwaves, 3-Axis Gauss or Tesla Magnetic Fields and Electrical ELF Fields

Arrived on time. Easy to use and does what it claims to do at a decent price.

It wasn't quite what I expected but compared to other meters it was reasonable value for what it does. It's all about price and requirements. It was neither bad nor good. It seems to pick up RF signals ok but I was hoping to be able to calibrate the alarm to only trigger on very high readings. Maybe you can do this but I couldn't work it out. I had a £300 meter once that was no different. The area I live in is so saturated with RF that these meters are virtually in constant alarm. If you live in the country it might be more useful but I struggled. I don't think it's bad for the money just not for me. By the way the one's the professionals use are £25,000 so don't think these types of units will ever really tell you that much but they can help detect hotspots I suppose but only if you don't live in one all the time. You could try one and use the excellent return policy if it isn't useful but it may well be for you. I'd avoid spending much more than this unless you are a professional. I don't think you'd get much more functionality unless you drop a few grand on a pro one.
