General Tools and Instruments' 4:1 IR Thermometer is built to offer four sensitivity levels to optimize voltage detection

General Tools and Instruments' 4:1 IR Thermometer with NCV Detector & Flashlight (VR40) is designed to embody innovation in several ways that benefit technicians, contractors and electricians. As an instrument built to have the functions Infrared Thermometer (IRT), Non-Contact Voltage (NCV) detector and flashlight. Plus, its size is created to make it a good field tool, whether at the top of a ladder or in a dark crawl space.

The VR40’s integral IRT is designed to provide a way to measure surface temperatures, so it’s made for HVACR professionals who need to determine the temperature of heating or cooling coils, or detect overload currents in motors, electrical conduits and junction boxes. Temperature readings are designed to be displayed in Fahrenheit or Celsius (-4° to 626°F/-20° to 330°C) on a four-digit LCD and are made to be held for 15 seconds.

General’s VR40 is built to offer four sensitivity levels to optimize voltage detection over four practical ranges (12 to 25VAC, 70 to 125VAC, 150 to 240VAC, 250 to 600VAC). The VR40’s lower sensitivity levels are made for taking the guesswork out of identifying the “hot” wire in a bundle. The instrument’s audible and visual alarms are constructed to make it immediately evident when voltage is detected. And because the tip of the VR40 can fit in the slots of 110VAC receptacles, it also is designed to indicate whether the receptacle is wired correctly or in reverse. The instrument’s LED flashlight is designed to place the IRT and NCV sensors together with the flashlight at the same end of the device for convenient operation.
