Detectors Provide Fast, Easy Testing for Energized Circuits
Simply touch the tip of VoltAlert Detectors to terminal strips, outlets or cords. When it glows red, you know there's voltage in the line. Small enough to conveniently fit in a shirt pocket. Detectors' outer surfaces are nonconductive for safety. Detects voltage even without metallic contact.
VoltAlert Detector (No. 51575) detects line voltage from 90VAC to 1000VAC.
VoltAlert Detector (No. 51576) is for control voltage from 24VAC to 90VAC.
