The object distance ratio is 12:1, and the measurement range is wider. When the distance between the temperature measurement gun and the object to be measured increases, the measurement area will increase accordingly Infrared sensor can be easily done without contact: no need for close contact, just hand-held one-key temperature measurement, easy to do The correct method of measuring water temperature and oil temperature: Do not let smoke and water vapor touch the temperature sensing area when the liquid is boiling, and the measurement angle is recommended to be around 45°~60° LCD backlight bright screen: backlight display function, no fear of changes in the external environment, easy to read the value Use 2 AAA batteries for battery life, easy disassembly and assembly, and longer battery life Specifications: Measuring range: -20℃-380℃/-4℉-716℉ Environmental operating range: 0℃-40℃/32℉-104℉ Measuring distance: D:S=12:1 Response time: 500 milliseconds gap 94% response Emissivity: preset 0.95 Automatic shutdown: automatically shut down if there is no operation in about 7s Batteries: 2 AAA batteries (Not included) Screen display: LCD backlit screen Low battery reminder: √ Infrared laser: √ ℃/℉ adjustable: √ Maximum and minimum values: √ HOLD data retention: √
