Features: Temperature gun- uses high-quality sensors and can measure within 0.5 seconds. The measurement accuracy is up to ±1.5%. The distance spot ratio of 12:1 means- you can measure targets at greater distances. The laser thermometer emissivity range- is 0.1-1.0, you can adjust the emissivity according to different materials. With high-low-temperature warning function. When the temperature exceeds the temperature you set, the HIGH-/LOW icon on the LCD-screen will flash and send out bibi audios, reminding you that the temperature is abnormal. Simply scan the surface- of your object, hold down the trigger of the infrared thermometer, and release to get live temperature readings anywhere between -4°F~1382°F (-20~750℃). MAX-/ HOLD data function; unit conversion (℉ / ℃); low battery indicator and 15-second automatic shut-down function help- to extend the battery life. The temp gun- thermometer is NOT suitable for human/internal body temperature use. The reading measured by the thermometer gun- is the surface- temperature of the object, or liquid, and cannot measure the internal temperature, so the measured temperature of humans- or animals will be incorrect.
