REVIEW: Magnetometer, professional Gauss meter, with external probe, great to measuring low frequency magnetic fields, not good for high frequency electric fields like phones, wifi, routers, etc.
This meter is good to measuring magnetic field levels of electrical and electronic equipment, thanks to small probe you can locate the precise point of emission.
PRODUCT FOR PROFESSIONAL USE ONLY !!
MY PERSONAL OPINION: Meter for electronic professionals only, not for people need measure magnetic levels in rooms, and homes.
