Feature:
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, a one-key lock of the radiation value, the LCD display of the values for easier reading.
Radiation assessment, remind you whether the radiation value is safe or not.
Easy on-hand operation, it's easy to carry and make field measurements.
