Measures high temperatures in °C or °F with your choice of Lasite® or Line of Sight Sighting. The Single-Wire, Loop Powered, 1 mA - 20 mA Analog interface carries both power and signal on one conductor strand. With the M20 series you'll also enjoy easy field calibration and emissivity adjustment. Infrared thermometers have the ability to measure temperature without physical contact. Every object emits radiant energy, and the intensity of this radiation is a function of its temperature. The infrared thermometer measures the intensity of radiation and thereby measures the temperature.

Infrared thermometers are currently used in a wide range of laboratory and industrial temperature control applications. Wahl Instruments has a full range of both Portable IR and Fixed IR
