Feature: Specification: This EMF Meter can test electric field strength and magnetic field strength to reach the optimal test result. It's widely used to test and learn electromagnetic radiation situation indoor and outdoor. Suitable to measure the electro-magnetic generated machine, measure low frequency appliance and high frequency radiation appliance. Features: One EMF Meter with Two Uses - Testing the electric field and the magnetic field strength at the same time. Measure Radiation - of TV, induction cooker, rice cooker, refrigerator, computer, appliances, electrical wires, etc. Sound-light Alarm - When the test result exceeds the safe value, the instrument will alarm automatically. Data Hold & 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. Measure the Environment Temperature - with 2 temperature units (℃ and ℉).
