You will need our Smart Sensor AS330 Non-contact Digital Infrared Thermometer (Battery Not Included) as your best assistant if you’re going to deal with some non-contact temperature measurement. The infrared thermometer adopts advanced optics to measure smaller targets at greater distance. It supports data hold function， conversion of Celsius/Fahrenheit temperature， 12 data store/recall function， 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 8 seconds. Worth a try!
