Features 1.【High Accuracy】Non-contact laser measurement and K-probe contact measurement with 13-point laser guidance and adjustable emissivity (0.1-1.0) for more accurate measurement. Adopts France HTU20 temperature sensor and laser head to simultaneously display ambient temperature/humidity, dew point, corruption temperature, object surface and internal temperature. 2.【Easy to use】Simply point the thermometer at the object you want to measure and click to get a reading. Distance to spot ratio of 12:1 allows you to measure objects at greater distances, the larger the object, the farther the measurement distance; the smaller the object, the closer the measurement distance. For high temperature, toxic or hard to reach objects, using this product can be safely measured, the range is -58°F~1472°F (-50°C~800°C).Specification Specifications: Model: IR02C Material: ABS LCD Display: Color LCD display D : S: 12 : 1 Radiance: 0.10~1.00 Response Spectrum: 8~14μm Laser: 1mW / 630-670nm Level 2 Response Time: 0.5S Automatic Shutdown: 30 seconds Service Temperature: 0℃~40℃ / -58℉~104℉ Storage Temperature: -10℃~60℃ / 14℉~140℉ Power Supply: 2 * 1.5V AAA batteries (Not included) Measurement Temperature Range: -50℃~800℃ / -58℉~1472℉ Precision: -50℃~0℃ / -58℉~32℉; ±3℃                  0℃~ 800℃ / 32℉~1472℉; ±(1.5%~reading +2℃ /4℉) Ambient Temperature Range: -10℃~60℃ / 14℉~140℉ Precision: ±1℃ (0℃~45℃) / ±1.5℃ (-10℃~0℃, 45℃~60℃)                ±2℉ (32℉~113℉) / ±3℉ (14℉~32℉, 113℉~140℉) Ambient Humidity Range: 0%~99% RH Precision: ±4% RH (20%~80%)                ±5% RH ( 0%~20%, 80%~99%) Item Size: 150 * 103 * 44mm / 5.91 * 4.06 * 1.73in Item Weight: 136g / 4.8oz Package Weight: 276g / 9.74oz Package Size: 19 * 12 * 5.5cm / 7.48 * 4.72 * 2.17in Package List strong Package List: /strong 1 * Infrared Thermometer 1 * K-Type Thermocouple Probe 1 * Carrying Bag 1 * User Manual (English)
