The Santronics 3000 is an always-on non-contact voltage tester that detects AC voltage from 50 to 1000 volts without touching a single wire. There is no on or off switch because the tester is designed to be ready the moment you need it. The calibrated sensitivity is precise enough to identify the hot wire in a junction box full of conductors without triggering false alarms from nearby neutral wires. A bright LED and audible beep give you instant confirmation through two senses so you never have to guess. The CAT IV certified polycarbonate body is built for professional environments and tough enough to survive years of daily use. This compact pen-sized tool fits in a shirt pocket and is designed and manufactured in the USA by the company that pioneered non-contact voltage detection technology.
