Guy's Magnets Magnet Testing Kit: Electronic Pole Tester + Pole Sensor Foil

This is a testing kit for all types of magnets and contains both Pole Sensor Foil and an Electronic Pole Tester. Electronic Pole Tester: Sensitivity: +/- 15mT on/off hysteresis Operating Temperature Range: 0C to +50C Storage Temperature -20C to +70C Battery information: 4 x LR44/A76 (1.5V each) included. Video instructions for battery insertion Includes pen top clip for convenience. All batteries are brand new and have been fitted and tested by us, immediately prior to dispatch This simple device gives a clear and simple indication of what pole is being measured at the tip of the device using two LEDs (Green=South, Red=North). It is both small enough to fit in the pocket and tough enough to withstand hard use. The LEDs are marked N and S making mis-reading the pole impossible.(Green=South, Red=North) This is an essential gadget for many industrial uses including the manufacture of pumps and guitar pick-ups. It is also believed (although unsubstantiated) that magnets used for magnetic therapy should have the south pole facing into the body. Supplied, fitted and tested with 4 LR44 (1.5V) batteries. Includes pen top clip for convenience.
