12:1 IR Thermometer with Type K - (IRT227)


Test Title

Sub Title


The Triplett Model IRT227 IR thermometer with Type K that can instantly measure the surface temperature of objects without making contact plus Type K and Air (ambient) Temperature. With a quick press of the trigger, a built-in laser identifies the measurement area, and the backlit LCD simultaneously displays the temperature of the target plus air temperature. In addition, the Type K thermocouple provides contact temperature measurements.It features a 12:1 distance to target ratio, wide temperature range of -58° to 1112° F (-50° to 600°C), adjustable emissivity, audible and visual high/low temperature alarms, Min/Max/Avg/Diff, and automatic data hold with power off after 10 seconds. Includes Type K bead probe and 9V battery. 1-year warranty.


IRT227-NIST Comes with Certificate of traceability to NIST standards
