Description: EMF Tester with two uses, testing the electric field and the magnetic field radiation 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, -key lock the radiation value. Large & clear LCD display of the values for easy reading. Easy to operate with easy -hand operation, easy to carry and make field measurement. Can measure the environment temperature with 2 temperature units ( and ).
