BETTER ACCURACY: 12: 1 D:S, meaning it can accurately measure targets at greater distances compared to most others; For best accuracy, the distance between the thermometer and object of measurement should approximately be 14.17 inches (36 cm)TARGET QUICKER: Measure surface temperature ranging from -58 to 716(-50 to 380), you can choose the unit from to ; Response time: 500Ms; A built in laser gives you the precision to hone in on the exact space you want to measureADDED FUNCTIONS: The LCD screen is backlit, also has an auto-off function to extend the battery life, and features a low battery indicator so you never accidentally run out of juice (battery included)VERSATILE DESIGN: Infrared technology makes it to measure the surface temperature of various objects especially temperatures above boiling points and below freezing points; Use it for cooking, ovens; AC, refrigerators; or soapmaking cats toy etc.NOTE: Temperature readings from this devices are inanimate objects. The measured temperature for humans or animals will not be correct.
