TM 192D 3 axix Magnetic Field Meter with Data Logger

Easy to use. Measurements are repeatable. I've learned to stay away from certain electrical products - especially those with motors. The only down side is that you become a bit paranoid after awhile. I measured the EMF in my friends Tesla - it was though the roof. It really psyched him out because he loves the car and has a major stock position in the firm.

Works well
