ROK 31310 70-1000 VAC Non-Contact Voltage Detector

The ROK 31310 70–1000 VAC Non-Contact Voltage Detector is a quick, safe, and reliable tool for identifying the presence of live voltage without making physical contact with wires or terminals. Designed for electricians, maintenance technicians, and DIY users, this compact tester senses AC voltage from 70 to 1000 volts (50/60 Hz) and alerts the user with both a bright LED light and an audible buzzer. It’s ideal for checking outlets, switches, circuit breakers, lighting fixtures, cords, and electrical panels before starting work.

Lightweight and powered by two included AAA batteries, this tester fits easily in a pocket or tool pouch, making it ready for use on the job site, in the workshop, or at home. Its non-contact design helps reduce the risk of electric shock while allowing for quick voltage checks in tight or hard-to-reach spaces.
