Extech DV25 Dual Range Non-Contact Voltage Detector - Adjustable AC Voltage Tester 12-600V & 100-600V, LED & Audible Alerts, CAT IV-1000V Safety, Pocket Clip

DUAL RANGE VERSATILITY: Detect voltage from 24V to 1000V AC or 100V to 1000V AC with a simple toggle. This sensitivity allows you to safely check low-voltage systems like thermostats and doorbells or high-voltage main lines with one professional tool.

AUDIBLE AND VISUAL ALERTS: Stay informed with a loud beeper and a flashing red LED that signals the presence of live voltage. You will not have to guess in noisy environments or bright sunlight since the dual-alarm system has your back every time.

BUILT-IN LED FLASHLIGHT: Illuminate dark corners, junction boxes, and cramped electrical panels with the integrated high-intensity light. Stop fumbling for a separate torch when you are trying to find a circuit; this pen lights the way to safety.

COMPACT PEN DESIGN: Clip this lightweight detector to your shirt pocket and take it anywhere. The rugged, double-molded housing is built for the job site, while the sleek pen shape ensures it is always within reach when you need to verify an outlet.
