EA Technology Instruments Polarity Test Kit
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 that the pen is working correctly by simulating the electrical field produced by a live conductor.
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.
