The Klein Tools IR5 Dual-laser Infrared Thermometer is designed for rugged field work. With a 6.6-foot drop protection range, you know you're carrying a reliable tool and not a delicate jewel. The generous measurement range is -22 to 752F (-30 to 400C) and distance-to-spot optical resolution ratio is 12 1. This thermometer features dual laser targeting, auto-scan, max/min/avg/diff and high/low alarm. The backlit display ensures visibility and auto power-off means no drained battery. Battery life expectancy is ten hours of continuous use with the laser and backlight on. The IR5 includes a protective custom pouch and battery.
