The Chex-Zit is the diagnostic tool that answers the two questions techs ask most - is this circuit continuous, and is it live - without dragging out a meter. A combination continuity and electrical current tester for low-voltage work up to 220V, it lights a bright red LED when it detects continuity (no open circuit) or voltage. Check fuses, find shorts in coaxial cable, verify speaker wire runs, and run routine diagnostics in seconds.
It is leadless - no wires or clips to untangle or lose - machined from aircraft-grade aluminum with a durable satin finish, and it carries a pocket clip so it rides in a shirt pocket like a pen. Powered by two AAA batteries, included.
