The Triplett IRT220 is a compact, rugged, easy to use non-contact IR thermometer that can instantly measure the surface temperature of objects without making contact. With a quick press of the trigger, a built-in laser identifies the measurement area, and the backlit LCD displays the temperature of the target. It features a 12:1 distance to target ratio, wide temperature range of -4° to 932° F (-20° to 500°C), fixed 0.95 emissivity, automatic data hold with power off after 10 seconds, and min/max recording. Includes 9V battery. For industrial use only. Not a medical device thermometer.
