New from EA Technology Instruments, the Polarity Test Kit enables engineers to identify live low voltage (LV) conductors accurately and in complete safety.
The kit comprises two parts – a Polarity Test Pen plus a Test Pen Checker, which automatically confirms the pen is working correctly by simulating the electrical field produced by a live conductor.
EA Technology instruments director Neil Davies explained: "The kit is designed to give electrical engineers total confidence when looking for live conductors, particularly in bundles of cables and crowded enclosures. The self-testing function is a unique and important safety feature."
Unlike general purpose conductor testers, the Polarity Test Pen is accurately calibrated so that its light and buzzer will only activate when the tip of the instrument is within 3mm of the live core of a standard 3mm conductor.
It can therefore discriminate between individual live and non-live conductors and does not require current flow in the live conductor.
Powered by two AAA batteries, it works with all standard 220-250V 50/60Hz supplies.
To confirm proper operation of the pen, users simply insert it in the Test Pen Checker, which is self-powered and activates automatically.
The maintenance-free Test Pen Checker also functions as a rugged carry case for the Polarity Test Pen and is supplied with a clip on lanyard.
The Test Pen Checker is fully compatible with the new Polarity Test Pen and the instrument it replaces, EA Technology's best selling Polarity Tester. Both the Polarity Test Pen and Test Pen Checker may be purchased separately.
