Santronics AC Sensor OSHA Approved
This hand held device is used for determining the presence or absence of AC voltage in insulated wires, wall receptacles, fuses, junction boxes, switches, and any other voltage-carrying electrical systems.
Simply touch the plastic tip to a connection point or move it along an insulated wire. If AC voltage is present the LED light in the probe tip will glow bright red. The illumination will stop at a break in the circuit or wire and this allows the AC Sensor to be used as a troubleshooting instrument.
