Are you going to deal with some non-contact temperature measurement? Take this Smart Sensor AS852B Non-contact Digital Infrared Thermometer (Battery Not Included) along to do yourself a favor! The infrared thermometer adopts advanced optics to measure smaller targets at greater distance. It supports max/min/dif/avg measurement mode selection， high/low temperature alarm setup， data hold function， conversion of Celsius/Fahrenheit temperature， backlight display for use in poor light areas as well as laser guided sighting system for easy targeting. Moreover， it will automatically shut off when there is no operation in a few seconds. The emissivity is also adjustable from 0.10 to 1.00!
