The FLIR VP52-2 is a rugged, CAT IV-rated non-contact voltage detector with light, vibration, and beeper feedback alarms, as well as a bright LED flashlight. The VP52-2 can be used to reliably check if an AC circuit is active before beginning work, detect voltage on exposed conducting parts or through insulation, identify live wires within electrical panels, switches, and outlets, or trace live wires and map circuits. The FLIR VP52-2, with its ergonomic and drop-tested design, is ideal for experts doing field troubleshooting and verification of electrical installations in residential, commercial, and industrial structures.
