Features 1. High accuracy: The distance to spot ratio is 12:1, meaning the infrared thermometer can accurately measure targets at a distance. 2. Fast measurement: Measures surface temperature ranging from -58F to 1022F (-50C to 550C); selectable C/F units; response time: 500 ms. 3. Added functions: Auto-off function helps extend battery life; low battery indicator alerts when battery power is low (battery not included). 4. Multifunctional use: This non-contact infrared thermometer is ideal for electrical, mechanical, HVAC, and automotive systems; also suitable for various industrial and daily applications such as cooking, refrigeration, metal, glass, plastics, and food processing. 5. Quickly and safely measures surface temperatures from a safe distance. Built-in red laser for precise aiming. The 12:1 distance to spot ratio allows accurate readings on distant targets. Portable and anti-slip design enables easy use both indoors and outdoors.
