The Tri-Field Meter Kit contains three different sensors which let you measure electric, magnetic and RF fields with the kind of coolness that Dr McCoy himself would envy. Some folk even think it can detect the presence of ghosts, but hey…we’re staying Casper agnostic, OK? All we know is those LED light arrays sure look purty. $74.95.
The technical applications are endless. Use it to detect radiation from monitors and TV’s, electrical discharges from appliances, RF emissions from unknown or hidden transmitters and RF sources, and a whole lot more! If your wondering whether your wireless project or even your cell phone is working, you can easily check for RF! A 3-position switch in the center allows you to select electric, magnetic, or RF fields. A front panel “zero adjust” allows you to set the sensors and displays to a known clean “starting point”.
