The Ultimate AC Sensor is a hand-held device for determining the presence or absence of 50-1000 volts AC in insulated wires, wall receptacles, fuses, junction boxes, switches and other voltage carrying electrical systems. It is not necessary to disconnect the system in question because no contact is required for operation and current flow is not necessary to locate voltage. Simply touch the plastic tip to a connection point or move it along a wire. If AC voltage is present, the tip will glow red and you will hear an audible tone,
The audible alert reacts ONLY to an AC voltage field and will not beep when it somes in contact with a static field.
There is no ON/OFF switch on the Ultimate AC Sensor . Switches can wear out over time or even malfunction. The Ultimate AC Sensor is alway on and ready to use!
Product is manufactured and packaged in the USA. Lifetime warranty.
