Features 1. The distance to spot ratio is 12:1, meaning the laser grip can accurately measure targets at greater distances compared to most other thermometers; for best accuracy, the distance between the thermometer and object of measurement should be approximately 14.17 inches (36 cm) 2. Measures surface temperature ranging from -58°F to 1112°F (-50°C to 600°C), with selectable temperature units; response time: 500 ms; a built-in laser provides precision for targeting the exact area to measure 3. Infrared technology allows for convenient surface temperature measurement of various objects, especially those above boiling or below freezing points; ideal for cooking, barbecuing, automotive maintenance, home repairs, and other applications Specifications: Temperature range: -50°C to 600°C (-58°F to 1112°F) Accuracy: 0°C to 600°C (32°F to 1112°F): ±1.5°C or ±2.7°F or ±1.5% of reading, whichever is greater -50°C to 0°C (-58°F to 32°F): ±3°C or ±5°F Resolution: 0.1°C or 0.1°F Repeatability: ±1% of reading or ±1°C (±1.8°F) Response time: 500 ms (95% response) Spectral response: 8–14 μm Emissivity: 0.1–0.99 adjustable Distance to spot size: 12:1 Operating temperature: 0°C to 50°C (32°F to 122°F) Operating humidity: 10% to 90% RH, non-condensing Storage temperature: -20°C to 60°C (-4°F to 140°F) Power: 1.5V AAA battery (2 required, not included) Typical battery life: 12 hours with laser off Package Includes: 1 x Infrared Thermometer
