Safety Protection:This EMF detector can test electric field ranges from 1 to 1999V/m and magnetic field ranges from 0.01 to 99.99µT/0.1 to 999.9mG strength simultaneously. It also measures ambient temperature from 32℉ to 122℉. (Note: This EMF meter cannot test RF values.)

Sound-Light Alarm: If the test result exceeds a safe level (0.4µT/4mG) or 40V/m), the EMF meter will emit a beep alarm (Beeping can be turned off), turn the screen red, and start flashing an indicator to alert you to high levels of radiation.

Multi-Functional: The EMF tester featuring a LCD backlit screen display, one-key hold for average or peak (Maximum) value reading, temperature unit switch, reset to zero, beep alarm switch, low battery indicator, and auto power off after 5 minutes of idleness.

Versatile Uses: The EMF detectors can be widely used to detect EMFs from various electrical appliances in home and workplace, such as TV, computer, microwave oven, refrigerator, outlets and light switches, etc
