Wide range of applicationThis laser thermometer gun is widely used in measuring the surface temperature of inaccessible objects: laser thermometer gun for cooking, pizza oven thermometer gun, infrared thermometer gun for cooking or reptiles. Better accuracy12:1 distance spot ratio, accurately measure targets at greater distances; The best distance between the laser temperature gun and object of measurement should approximately be 14.17 in (36cm). Pull the IR thermometer gun trigger and hold it for 2-3 seconds for a more accurate reading. ConvenienceThis infrared laser thermometer has a COLOR LCD screen with a backlight; MAX / HOLD data function; unit switch ( C); Low battery indicator and 30-second automatic shutdown function (battery included). Adjustable EmissivityThe emissivity range of the temp gun is 0.1-1.0, which allows for adjusting the emissivity according to different materials for the most accurate area measurement; Measure temperatures at the range of -50C - 600C. WarningThis IR laser thermometer gun is for use on surfaces, NOT for humans. This infrared heat gun thermometer can not measure the internal temperature of an object; Do not irradiate human eyes directly or indirectly with infrared rays at any time.
