Klein Tools NCVT1P Non-contact Voltage Tester 1000V

Product Description

The KLEIN TOOLS NCVT1P is a non-contact voltage tester rated for 50 to 1000 volts AC, designed for fast, safe detection of live voltage without direct contact with conductors. A bright green LED confirms the unit is powered and ready. When voltage is detected, a bright red LED activates alongside an audible warning tone, giving both visual and audio confirmation. The tester uses a microprocessor-controlled circuit with a low battery indicator and automatic shutdown to preserve battery life. Built from durable polycarbonate plastic resin, it is compact and lightweight enough to pocket on the job.

The NCVT1P is suited for residential and commercial electrical work. Electricians and service technicians use it to check cables, cords, circuit breakers, lighting fixtures, switches, outlets, and wiring before beginning work. The CAT IV 1000V safety rating makes it appropriate for use at the service entrance level as well as branch circuit and outlet testing. Its pocket clip and compact form factor make it a standard carry tool for daily electrical service calls.

Installation Notes

The NCVT1P is a diagnostic tool installed and used by licensed electricians and qualified service technicians. Before testing any circuit or component, follow applicable NFPA 70E arc flash and shock hazard protocols. Always verify the tester is functioning correctly by testing a known live source before relying on a no-voltage reading. Do not use this tester as the sole means of lockout/tagout verification on high-energy systems.
