Multimeters & Test Equipment

A multimeter is the instrument that turns a suspicion into a reading, and the rest of this range exists for the same reason: to prove what a circuit is actually doing before anyone signs it off.

The range covers multimeters and voltage testers for general electrical work, socket and installation testers for verification, and specialist alignment tools — the GJD D-TECT walk testers for setting PIR coverage, and signal-strength testers for wireless detection. Contact cleaner and consumables sit alongside them. Mercury leads the range with Knightsbridge and GJD.

Test gear is bought against the work it verifies. For detection alignment see Smart Alarms & Sensors, and for the installation hardware being tested Outdoor Electrical Boxes. Range, category and battery type are stated on each product page.
