Digi-Sense, WD-20250-06, 20:1 IR Thermometer with Alarm & NIST Traceable CalibrationIncludes:20:1 IR ThermometerOne 9 V battery and NIST-traceable calibration report with data supplied by InnoCal. Infrared thermometers have become the preferred tool for diagnostics and inspection where temperature is an indicator. Digi-Sense infrared thermometers are valued by professionals in a variety of industries - from industrial maintenance to foodservice - because they quickly, accurately, and safely measure surface temperature. Plus the NIST-traceable precalibration means you get reliable measurements right out of the box, saving you time and money! Since infrared (IR) meters do not contact the objects being measured, they are the safest way to measure hot, hard-to-reach, or moving parts while eliminating potential damage and contamination. IR thermometers are easy to use: just pull the trigger and the temperature will show in an instant on a large, backlit display. All models feature Min/Max and Hold functions, °F/°C selectable units, single targeting laser, large backlight LCD, and auto power-off. Models 20250-05 and -06 also offer adjustable emissivity and user-adjustable temperature alarm with indicator light. Model 20250-06 has all the standard features plus a distance-to-sight ratio of 20:1, temperature range of -31 to 1472°F (-35 to 800°C), adjustable emissivity, and user-adjustable temperature alarm with indicator light.Features:Safely and easily locate hot and cold spots, preventing problems and saving costsReliable measurements, guaranteed!
