Features Surface Temperature Measurement: The infrared thermometer can be used to measure the surface temperature of inanimate objects, reading up to ±5% of the value with high accuracy within 2.0s. LCD Screen with Backlight: The digital temperature gun has an LCD screen with backlight to distinguish data at a glance. Maximum or hold data function, low battery indicator and 5 second auto shutdown function. Temperature Alarm: The pyrometer has a maximum mode and a high or low temperature warning function. When the test temperature exceeds the high or low limit setting, the indication turns red. Emissivity Adjustment : You can adjust the emissivity of the digital handheld pyrometer from 0.1 to 1.0 for the most accurate value depending on the material. Wide Application: This digital temperature gun is widely used for daily and industrial temperature measurement, such as cooking, home maintenance, HVAC problem, soap making, water temperature measurement, etc. Specification: Item Type: Infrared Thermometer Material: ABS Battery: 1.5V AA Battery x 1 (Shipped Without Battery) Temperature: -50 - 550℃ (-58 - 1022℉) Accuracy: ±1.5℃ Or 1.5% Whichever Is Higher Side Measurement Distance: D:S Equal To 12:1 (Measurement Conditions: Vacuum Medium) Maximum Display: 3 Digits Automatic Shutdown: 20 Seconds Sampling Rate: ≤0.5sec Backlight: Yes Low Battery Display: Yes Data Hold Function: Yes Maximum Or Minimum Value Or Average Difference Value: Yes High Or Low Temperature Alarm Function: Yes 0℃ Offset Adjustment: Yes Unit Sign Display: Yes Power Consumption: ≤50mW Package List:1 x Industrial Thermometer  1 x Instruction Manual Note:Do not use it to measure for forehead temperature, human measurements will be incorrect.
