The Extech 42545 is a professional-grade infrared thermometer designed for non-contact temperature measurements in demanding industrial, HVAC, and maintenance applications. With a wide range of -58°F to 1832°F (-50°C to 1000°C), a high 50:1 distance-to-spot ratio, and dual laser targeting, it accurately measures small or hard-to-reach surfaces from a safe distance. Features include adjustable emissivity, visual/audible Hi/Lo alarms, MIN/MAX/AVG/DIF functions, and a backlit display for low-light conditions.
