Great for Electromagnetic Noise Detection

Tuning this portable AM radio to a station-free dead zone makes it a great device for sniffing out kHz range magnetic fields typically produced by dimmer switches, LED displays, fluorescent lights, TVs, DVDs and computers. These frequencies could be missed by a standard 50/60 Hz gaussmeter. The loudness of the static corresponds to the strength of the field and you can easily hear the frequency of the signal, and distinguish many different tones. Requires no practice or training. Just turn it on and walk around your home or office. Uses 2 AA batteries (not included) and measures only 2 x 3.5 inches. Has a jack for headset (not included) and can also be used for listening to AM/FM radio. Locate EMF offenders that might not otherwise be obvious: AC/DC transformers, alarms clocks, power strips, smoke alarms, cash registers, fish tanks, spark plugs ……
