2.8'' Outdoor Electromagnetic Radiation Detector

Our EMF metre comes without 6F22 9V Heavy Duty Batteries. Please prepare on your own! As there may be a disturbance of electromagnetic field in the environment, when starting up, the EMF detector may give a small reading. It is a normal phenomenon. Hold the instrument to make the inductive zone at the front end get closer to the electromagnetic radiation source to be tested slowly. Distance measuring shall be made for high-voltage facilities.
