Extech Instruments MD10 Non-Contact Magnet Detector with Flash Light

Very helpful to check solenoid coils active.

A must have when trouble shooting in the oil field, a simple and effective tool that’s easily carried.

Very handy for maintenance technician, fast and efficient at identifying if solenoid is energised

Does what it says on the tin. What it didn't say was you can't use it in dangerous environments where gases may be present.

Works very well

fits in pocket, easy to use. works very well and seems to be decently built. I've been using one in an industrial setting for over a year and the only thing I've had to worry about was my colleagues stealing it for themselves! worth the purchase price.

Fonctionne parfaitement

Good but expensive
