measurement area while maintaining the measurement angle around 45°~60°.【Emissivity Adjustable】: 0.1-0.99 adjustable emissivity, for accurate readings on various different organic materials and painted or oxidized surfaces. The emissivity is preset to 0.95 in the thermometer.【12: 1 Object Distance Ratio】: 12: 1 object distance ratio, with larger measurement ranges. As the distance between the instrument and the object being measured increases, the measurement area increases accordingly.【Wide Applications】: Industrial thermometer design, can not measure the body temperature of animals, adults, and children. Can be widely used in various industries to measure high temperature on the surface of the object. Applicable to machinery manufacturing, ceramic firing, light industry, gold, automobile industry, food cooking, mold temperature measurement, household water temperature and oil temperature measurement, and so on.Specifications:Name: Laser Infrared ThermometerMaterial: ABSBattery: 2 * AAA batteries (not included)Measurement ranges: -50℃ to 530℃, -58℉ to 986℉Temperature measurement accuracy: ≥100℃, ±2%; ≤100℃, ±2℃Response time: 0.5 secondsAdjustable emissivity: 0.1-0.99Measuring distance ratio: 12:1Resolution: 0.1℃ (0.1℉)Battery undervoltage: Support℃/℉ conversion: SupportBacklight display: SupportLaser sighting: SupportMenu function selection: SupportOperating temperature: 0℃-50℃Relative temperature: 10-95%RH (non-condensing)Storage temperature: -20℃ to 50℃ (-4℉ to 122℉)Operating temperature: 0-50℃ (32-122℉)Item size: 150 * 89 * 40mm / 5.91 * 3.50 * 1.57inItem weight: 145g / 5.11ouncePackage size: 170 * 105 * 45mm / 6.69 * 4.13 * 1.77inPackage weight: 185g / 6.53ouncePacking List:1 * Laser Infrared Thermometer
