EA Technology Instruments has brought out the Polarity Test Kit, which allows engineers to accurately and safely identify live low voltage (LV) conductors.
The kit comprises a Polarity Test Pen and a Test Pen Checker, which simulates the electrical field produced by a live conductor to confirm the pen is working.
The kit comprises of a Polarity Test Pen and a Test Pen Checker, which simulates the electrical field produced by a live conductor to confirm the pen is working.
The Polarity Test Pen is calibrated so 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 need current flow in the live conductor.
It is powered by two AAA batteries and 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.
The Test Pen Checker can be used as a carry case for the Polarity Test Pen.
The Test Pen Checker is supplied with a clip-on lanyard.
