ELECTRONIC POLE TESTER

Price / Quantity Breaks

Description

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.

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.
