Chex-Zit™ - Continuity Tester

The Chex-Zit™ is a combination continuity and electrical current tester used for performing routine diagnostics on circuits and wiring (both high and low voltage applications).  The Chex-Zit is made of aircraft grade aluminum and buffed to a durable satin finish.   A bright red LED indicates when continuity (no open circuits) or voltage is detected. 

Features include:

  • Leadless, meaning no additional wires or clips are needed
  • Includes a pocket clip so your Chex-Zit is always available for service
  • Powered by 2 AAA batteries (included)

Use the Chex-Zit for checking Continuity in alarm or other circuits, verify good Earth grounds, transformers or other electrical wiring.

Installers Tip:

When diagnosing AC wiring (up to 120 volts) the Chex-Zit’s LED glows brighter on the “hot” side
