The Extech DV40 AC Voltage Detector + IR Thermometer is a tool that can detect AC voltage and measure temperature. It can detect AC voltage from 50 to 1000V and has a built-in infrared thermometer that measures temperature from -20 to 445°F (-30 to 230°C).
The EXTECH DV40 is a handheld instrument combining a non-contact AC voltage detector with a built-in infrared thermometer. It is designed to quickly check for the presence of live wires and measure surface temperatures without physical contact.
The device features a 9,999 count LCD display with selectable Fahrenheit or Celsius units. It includes a rugged double molded housing, a pocket clip, and comes with three LR44 batteries. The unit automatically powers off to conserve battery life and features a low battery indicator.
