Detect The Presence Or Absence Of Voltage!
The Model 7929 AC Sensor provides non-contact verification that a voltage is present. The tip glows bright red when voltage is detected. The AC Sensor is an ideal way to make sure there is power going to your ionizer. It can also be used to test wall receptacles, switches, fuses, junction boxes and more. It is even possible to locate electricity through insulation, making it ideal for finding breaks in power cords and wires. The tip glows bright red and an audible tone is heard when voltage is detected.
