Features 1.High accuracy: The distance to spot ratio is 12: 1, meaning the temperature meter grip can accurately measure targets at great distances. 2.Target quicker: Measure surface temperature ranging from -58℉ to 1022℉/ -50℃ to 550℃, you can choose the unit from ℉/ ℃; response time: ≤500Ms. 3. Added functions: The thermometer has an auto-off function to extend the battery life, and features a low battery indicator so you never accidentally run out of juice (battery not included). 4. Multifunction: This infrared thermometer for noncontact surface temperature measurement is great for use in monitoring electrical, mechanical, HVAC and automotive systems, also can be used in daily and industrial temperature measurement, such as cooking, refrigeration, steel, glass, plastics, food and so on. 5. Easily and quickly measures temperatures from a safe and hazard-free distance. NOTE: The diameter of the object under test must be bigger than the laser spot size. Built-in red laser for precisely aiming. The Distance to Spot Ratio is 12:1, meaning this infrared thermometer can accurately measure targets at long distance target. Portable and anti-slip design makes it easy to get the temperature outdoors and indoors.
