The Chex-Zitâ„¢ 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.
Leadless, meaning no additional wires or clips are needed
Includes a pocket clip so your Chex-Zit is always available for service
