  • Description

    Extech DV40 NCV Voltage Detector + IR Thermometer

    The Extech DV40 combines two functions together into one small and very light weight volt tester (only 42g).

    By being able to carry out Non contact temperature measurements from -30 to 230°C (-20 TO 445°F) the Extech DV40 can be extremely useful when trying to locate burning/arcing contactors or circuit breakers just by looking for the heat source, or to check performance on electrical components without having to swap equipment during inspections which also makes this time saving.

    The Voltage Detector probe, the white transparent tip is there so the detector can be placed next to insulated cables for detection of AC Low Voltage (50 to 1000V) which will light up and sound when voltage is detected.

    With the DV40 being housed in a rugged double mould the detector is built with evident drops and falls in mind so it has more protection. The Thermometer is compact and yet accurate, with the distance to target ratio being 1:1, which when elaborated upon means the object your aiming at should be proportionate to the diameter of the infrared laser.
