This self-testing kit comprises of 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. It is designed to give electrical engineers total confidence when looking for live conductors, particularly in bundles of cables and crowded enclosures.

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 conductor

It can therefore discriminate between individual live and non-live conductors and does not need current flow in the live conductor.

Features:

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.
Pen lights up and buzzes when it detects the electrical field surrounding a live LV insulated conductor
Lights up ONLY within 3mm of the live core of a standard conductor
Works with all standard 220-250V 50/60Hz supplies
Does not require current flow in the live conductor
Rugged construction with pen-style pocket clip
The pen is powered by two AAA batteries
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.

Benefits:

Discriminates between live and non-live conductors - even in bundles of cables
More accurate than other standard conductor testers
Self-testing function ensures correct function and operator safety
Self-powered, portable and easy to use
Considered to be essential to operator safety
