AC Voltage and Current Detector is Two Tools in One Compact Instrument
Trace concealed wires in walls and floors. EXTECH Noncontact AC Voltage and Current Detector identifies hot wires and traces current flow behind walls and in conduit. Current sensor detects live circuits through shielded wires, conduit and metal circuit breaker / junction boxes. AC voltage detection: 12–600V AC. AC current detection: 200mA–1000A. Sensitivity adjustments increase or reduce sensor trigger threshold. Detects current flow of 400mA at 0.2" and at much greater distances for larger current flows. Audible and visible indicators. Includes pocket clip and four LR44 button batteries.
