Feature: Unit can be Switched: Celsius/Fahrenheit units are optional and can be switched with one button. Backlit Display Function: Press and hold the test switch and function key to select backlight on or off. Industrial Temperature Measuring Gun: The temperature measuring gun is used to measure the surface temperature of objects, such as cooking surface food, industrial temperature measurement, etc., and cannot be used for human body temperature measurement. Higher Accuracy: The ratio of distance to test point is 12:1, which means that the target is accurately measured at the same distance in a smaller measurement area. Faster Response Time: Response time is 500msec, corresponding speed is faster, no need to wait.
