Extech DVA30: Non-contact AC Voltage and Current Detector
Detects and pinpoints wide range Voltage and Current with Sensitivity adjust
The DVA30 is the only two-in-one current/voltage detector designed for electrical testing. It detects AC voltage from 12-Volt to 600V and AC current from 200 mA at 0.2 in. distance and at much greater distances for larger current flow up to 1000 Amps. Sensitivity adjustments increase or reduce sensor trigger threshold. Audible and visual indicators show the presence of current or voltage. It can be used to trace concealed wires in walls and floors, identify hot wires, trace current flow where voltage detection does not work (behind walls, in conduits, through concrete, or underground). The sensitivity is high enough to trip on low voltage HVAC or similar signal levels. Complete with four LR44 button batteries and pocket clip.
