Tools and Hardware Reviews of Extech 480823 Electromagnetic Field and Extremely Low Frequency Meter
Customer Review: EMF meter
Summary: 1 Stars
i was looking for a triple-axis meter, not a single-axis meter. The product was extremely expensive for a single-axis meter, too! The meter did not work very well. I put it to an electrical machine, and it just said .01 mg almost all the time. When I put it to a hair dryer, the measurement always changed. First it was 21 mg, then it was 16 mg, and then it was 34 mg. It was always changing. I needed this meter for a science project and it failed the requirements.
