About this product
A TOTAL voltage test pencil with a 3 x 140 mm slotted shaft, designed to detect AC voltage in the 100 to 500 V range. Electricians and technicians use it to confirm whether a socket, switch or wire is live before working on it. It is a test tool only and does not measure the exact voltage.

Frequently asked questions
Can I use this pencil to test DC voltage?
The listing specifies AC 100-500 V only, so it is not specified for DC. Use a multimeter for DC measurements.
How should I use it safely?
Test the pencil on a known live source before and after testing a circuit to confirm it works. Never rely on a test pencil alone, and follow standard electrical safety practice when working on mains circuits.
