Polarity Tester

Chicago October 10. 2008

IEM introduces the PT-1 Polarity Tester for bobbin and free wound coils. The tester uses a magnetic field to energize the coil under test, and it then compares the coil output to the original signal. A red / green LED indicates the relative polarity of the coil. The PT-1 is easy to use and gives a reliable indication. It is useful for verifying the relative polarity of motor field coils and of polarity sensitive solenoid type windings.

IEM has been building coil testing equpment since 1976. We offer a line of shorted turns testers and turns counters for bobbin and toroidal windings.
