ERICKHILL EMF Meter, Rechargeable Digital Electromagnetic Field Radiation Detector Hand-held Digital LCD EMF Detector, Great Tester for Home EMF Inspections, Office, Outdoor and Ghost Hunting(Blue)

【PRECISE MEASUREMENT】 The built-in electromagnetic radiation sensor displays the radiation value on the clear LCD digital display after processing by a control microchip. It can test magnetic field radiation with optional units mG/µT and the electric field with unit V/m. However, this EMF meter cannot test the RF value.Electric field Range: 1V/m-1999V/m,Alarm threshold: >40V/m.Magnetic field Range:0.01μT-99.99μT / 0.1 mG - 999.99 mG,Alarm threshold: >0.4μT / 4mG.
【SOUND-LIGHT ALARM】When the testing result exceeds the value (0.4µT (4mG) or 40V/m), the screen will turn red, the indicator will flash, and the buzzer will sound an alarm. If you are testing in quiet areas, you can close the buzzer first to avoid disturbing others.
【MULTIFUNCTION】The meter can test average or peak value (Maximum) reading and hold the data for a view with a single key. Please make sure to confirm whether the hold key is pressed when measuring again. If "H" is displayed on the screen, cancel first and then measure again. The large backlit LCD provides clear viewing. The meter has an auto power-off feature after 5 minutes without operation.
