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: 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; Dual targeting lasers offer more accurate determination of the area being tested; Optical Resolution (Distance-to-Spot) is 20:1; Measurement range for both IR and K-Type probe -40 to 1200-Degree Fahrenheit (-40 to 650-Degree Celsius); Not a medical device; thermometer is NOT intended for use on people or animals.; Adjustable emissivity from 0.1-1.0 delivers flexibility to address multiple applications; Bright backlit display for working in low ambient lighting conditions; Statistical parameters for measurement event - max/min/avg/diff; User definable high/low limits with audible and visual alarms when limits are breached; Uses one 9-volt alkaline battery, with battery life expectancy at 8 hours of continuous use with laser and backlight on; Includes custom pouch, K-Type probe and battery; Soft-touch, over-mold housing; built to withstand a 9.9-Foot (3 m) drop; \"Auto Power-Off\" conserves and extends battery life; IP54 ingress protections for dust and water resistance; U.S. patent D791,624; 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; Auto Power-Off conserves and extends battery life - Warnings: Read, understand and follow all instructions, cautions and warnings attached to and/or packed with all test and measurement devices before each use.; 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. - Replaced By Products: 69435
