Infrared Thermometer Non-contact Digital Laser Temp Meter Industrial Electronics Description: Infrared thermometer can be used both daily and industrial temperature measurement, such as cooking, refrigeration, steel, glass, plastics, food and so on., NOTE: The measured temperature for humans or animals will not be correct.) °C/°F switchable, automatic data hold, backlit LCD, low battery indicator, auto power off function. Battery is included. Easily and quickly measure 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. Distance Spot Ratio: 12:1, great to measure a long distance target. Measurement range: -50°C to 550°C/-58°F to 1022°F; Portable and anti-slip design makes it easy to get the temperature outdoors and indoors. Size: 6.30" (L) x 3.70" (W) x 1.61" (H)  Temperature range: -58°F to 1022°F /-50°C to 550°C Accuracy:  ± 9°F (-58°F to 4°F); ± 2°F (4°F to 1022°F)  ± 9°C(-50°C to -20°C); ± 2°C (-20°C to 550°C) Resolution: 0.1°F / 0.1°C Emissivity: 0.95 (fixed value) Distance Spot Ratio: 12:1 Spectrum response: 8 to 14 μm Operating temperature: 32°F -122°F /0°C -50°C Storage temperature: -4°F -140°F / -20°C - 60°C Operating humidity: 10%-90% RH Storage humidity: < 80% RH Power supply: 2 x AAA battery Package include： 1*   Temperature gun 2*  AAA battery 1*   User manual
