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.
