About This Product

The tester is used to find the magnitude of electromagnetic field radiation produced by power lines, computer monitors, TV sets, video machinery and similar devices. Measurements are taken through the separate probe, so the reading can be made away from the main instrument, and the accuracy figures were tested under 50 Hz or 60 Hz. The Electromagnetic Field Tester can be exported to customers in Mali, Benin, Nicaragua, Guyana and Uruguay.

Frequently Asked Questions

What units does the Electromagnetic Field Tester read in?
