DescriptionFeatures:100% brand new and high quality100% brand new and high qualityThis EMF Meter can test electric field strength and magnetic field strength to reach the optimal test result.Its 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.One instrument with two uses, it can test the electric field and the magnetic field radiation at the same time.Sound-light alarm, when the test result exceeds the safe value, the instrument will alarm automatically.Data locking, one-key lock of the radiation value and easily read the value.Measure the Environment Temperature-with 2 temperature units ( and ).Radiation assessment, remind you whether the radiation value is safe or not.
