Features 1. High accuracy: The distance to spot ratio is 12:1, allowing the infrared thermometer to accurately measure surface temperatures from a distance. 2. Fast temperature measurement: Measures surface temperatures ranging from -58°F to 1022°F (-50°C to 550°C); selectable °C/°F units; response time: 500ms. 3. Enhanced functionality: Features auto-off to conserve battery life and a low battery indicator to ensure reliable operation (batteries not included). 4. Versatile use: Ideal for non-contact surface temperature measurement in electrical, mechanical, HVAC, and automotive applications; also suitable for industrial and household uses such as cooking, refrigeration, metal, glass, plastics, and food processing. 5. Safe and efficient: Enables quick and accurate temperature readings from a safe distance. Built-in red laser for precise targeting. The 12:1 distance to spot ratio ensures accurate long-distance measurements. Portable, ergonomic, and anti-slip design for comfortable use in indoor and outdoor environments.
