Tenmars TM-191

64,90

REVIEW: Made by the known brand Tenmars,  this good magnetic field detector.
Good to measuring magnetic field of power lines and electrical networks at low frequency (50hz-300hz)
Not good to measuring electric field of radio networks like phones, repeaters, wifi, routers, etc…
powered by 9v battery, working time 12 hours

MY OPINION: it’s a good meter, with low price but good quality, the measurements are quite accurate, Tenmars keep a cheap but good standard, for retail users, recommended!
