The M12 Laser Temp-Gun™ Thermometer for HVAC/R (NIST) is a heavy duty pistol grip infrared thermometer for professional HVAC/R commercial and industrial applications. Powered by the Milwaukee M12 Lithium Ion battery, the 2277-21 can safely measure temperatures between -22 to 1472° F (-30 to 800° C) with a 40 to 1 distance to spot ratio for even the most demanding industrial applications. In addition, the M12 Cordless Laser Temp-Gun™ Thermometer for HVAC/R was designed with embedded non-contact voltage detection and an extra bright LED flood light to increase end user productivity. A NIST Certificate of Calibration with Data is also included, needed by many organizations as proof of calibration with the date when NIST Calibration was performed. The 2277-21 is covered by the Milwaukee 5-Year Warranty.
