The Amprobe TIC 300 PRO high voltage detector kit is a non-contact voltage detector for detecting alternating current (AC) on transmission lines, power distribution equipment, downed power lines, fuses, electrical outlets, and other power lines. It detects voltages in low, medium and high voltage applications (30-122kVAC) with bright visual and loud alerts. It is rugged and reliable for utility, industrial, heavy manufacturing and mine safety applications. The TIC tracers get thrown around in utility trucks, but the units are built to withstand the rough treatment.

The TIC 300 PRO has a low-voltage setting (30 to 1,500VAC) for checking voltage presence in breaker panels, breakers, power outlets and wiring. It also has a high-voltage setting (1,500 to 122,000 VAC when used with the included TIC 410A Hot Stick attachment) for checking transmission lines, downed power lines and substations. The presence of AC voltage is indicated by an LED light and audible beeper. It is MSHA certified and intrinsically safe. The TIC 300 PRO has a self-test that erifies the tester works properly and is drop-proof up to 6 feet.
