Description
The Extech DVA30 is the only two-in-one current/voltage detector designed for electrical testing. It detects AC voltage from 12 volts to 600 V and AC current from 200 mA (0.2 in. away) to large current flows, up to 1000 amps, at a distance. The sensitivity adjustment increases or decreases the sensor's activation threshold. Audible and visual indicators show the presence of current or voltage. The DVA30 can be used to trace hidden wires in walls and floors, identify hot wires, trace current flow behind walls, in conduits, through concrete, or underground. Sensitivity is high enough to trigger on low-voltage HVAC or similar signal levels. Includes pocket clip and four LR44 button batteries.
