Klein Tools IR10 is a professional dual targeting laser infrared (IR) thermometer. It offers a wide measurement range, a tight 20:1 distance-to-spot ratio, dual targeting lasers, and several calculation modes to facilitate different temperature measurement applications. In addition to measuring temperature using IR emission, it can also measure temperature using a standard K-type probe.Features Bright backlit display for working in low ambient lighting conditions Statistical parameters for measurement event - max/min/avg/diff Soft-touch, over-mold housing; built to withstand a 9.9-Foot (3 m) drop U.S. patent D791,624 Not a medical device; thermometer is NOT intended for use on people or animals. Auto Power-Off conserves and extends battery life Includes custom pouch, K-Type probe and battery User definable high/low limits with audible and visual alarms when limits are breached Adjustable emissivity from 0.1-1.0 delivers flexibility to address multiple applications Dual Targeting Lasers, 20:1 Distance-to-Spot Ratio; Hi/Low Limits with Simultaneous Audible and Visual Alarms When Limits are Breached; Bright Backlit Display; Works with K-Type Probe Also Uses one 9-volt alkaline battery, with battery life expectancy at 8 hours of continuous use with laser and backlight on Dual targeting lasers offer more accurate determination of the area being tested Optical Resolution (Distance-to-Spot) is 20:1 Incorporates surface temperature measurement capability using IR emission and can also measure bulk temperatures of air, gas, or liquids using a standard K-Type probe Measurement range for both IR and K-Type probe -40 to 1200-Degree Fahrenheit (-40 to 650-Degree Celsius) IP54 ingress protections for dust and water resistance Warnings LASER RADIATION, Class 2 laser. Do NOT stare into beam. Exposing eyes to laser radiation can result in severe and permanent eye injuries. NEVER look directly into the laser beam emitted by this instrument. Thermometer is NOT intended for use on people or animals. Usage of this tester in any way other than that specified by the manufacturer can impair safe operation, resulting in severe injury or death. Read, understand and follow all instructions, cautions and warnings attached to and/or packed with all test and measurement devices before each use.
