Handheld Mini Digital LCD EMF Tester Electromagnetic Field Radiation Detector Meter Dosimeter Tester Counter This meter can test magnetic field emission to reach the optimal test result. It is used to test and learn electromagnetic radiation situation indoor and outdoor. It is equipped with a built-in electromagnetic radiation sensor, which can display the radiation value on the LCD digital display after processing by control micro-chip. Features: One EMF Tester for testing the magnetic field radiation and temperature at the same time. Measure radiation of high voltage power lines, appliances, electrical wires. Sound-light alarm, when the test result exceeds the safe value, the instrument will alarm automatically. Data hold and max measurement, one-key lock the radiation value. Large & clear LCD display of the values for easy reading. Easy to operate with easy one-hand operation, easy to carry and make field measurement. Can measure the environment temperature with 2 temperature units (℃ and ℉).
