Dual-laser targeting makes this infrared thermometer temperature gun easier to visualize the area being measured, resulting in higher precision than single laser, measure surface temperature ranging from -58F to 1022F (-50C to 550C).2 Measurement modes: Provide two ways of temperature measurement: infrared non-contact and K type thermocouple probe. Making this laser thermometer gun more fitable to use in different situations.More fouctions: Temperature and Humidity Measurement. Two led light make you easier to use in darkness. NCV function to detect ac power. Colorful LCD screen has good viewing angle and better display than normal LCD screen. Low battery indicator and 30-second automatic shut down function. C/F switchable. MAX / HOLD data function. A 9V 6F22 battery is included.The adjustable emissivity is 0.1-1.0, which can measure the surface temperature of different objects more accurately. Distance to spot ratio is 12:1, which means you can easily and quickly measure temperatures from a safe and hazard-free distance. For the best accuracy, the infrared thermometer gun should be 14 in/36 cm away from the object.infrared thermometer gun can be used both daily and industrial temperature measurement, such as BBQ, cooking, baking, frozen food, fried food, grilling, pizza oven, machine, automotive, refrigeration, steel, planting, fire monitoring, home appliance temperature measurement. Warning: This infrared thermometer is NOT for humans temperature measurement.
