Measure range from -50℃~600℃ makes this temperature thermometer can help you do any task confidently in any time, and it made of fine quality material, practical, easy to operate and use, has a long service life. Come on and try it.   Features: Intelligent temperature measurement, no more than 0.5s, the test speed is very fast.  Built in infrared laser aiming,object distance ratio is 12:1, temperature unit can conversion from ℃ to ℉, real time continuous temperature measurement.  Scanning monitoring, where to scan and where to measure, really time display of temperature. Press and hold the key do not release it, it can scan the temperature in real time.  Automatic shutdowm: at the end of temperature measurement, automatic shutdowm in 6 seconds, reduce battery consumption.  Object distance ratio is 12:1,only when the temperature sensing area is aligned with the measured object can the accurate measurement be made.  A wild range of applications, classic design ultra clear LED screen.  Fast power on: hold the trigger and start the machine immediately, it does not take a second, release the trigger, no operation, 6 seconds automatically shut dowm.  Press the "emit" key to select the emissivity setting, press the "select" key repeatedly to select the emissivity setting.  Emissivity adjustable: according to the situation, the emissivity of the machine can be adjusted to achieve higher measurement accuracy.  A wild range of applications: food processing industry, industry field, refrigerator in life and other more temperature test.  Emergy saving and environmental protection, high and low temperature alarm, centigrade and fahrenheit, LED LCD backlight, low voltage prompt.   Specifications: Material: ABS;  Color：black;  Model: ET6532;  Emissivity adjustable: 0.1~1.0;  Object distance ratio: 12:1;  Emissivity: 0.1~1.0 adjustable;  Response time: ≤500ms;  Measurement error: ±2.0℃±2%;  Resolving power: 0.1℃/℉;  Power consumption: ≤50mw;  Measuring range: -50℃~600℃;  Ambient temperature: 10℃~30℃;  Storage temperature: -10℃~40℃;  Relative humidity: ≤90%;  Battery: 2*1.5v AAA battery (not included);  Item size:180 * 97 * 48mm / 7.1 * 3.8 * 1.9in;  Item weight: 120g / 4.2ounce;  Package size: 220 * 120 * 50mm / 8.7 * 4.7 * 2.0in;  Package weight: 128g / 4.5ounce;   Packing List: 1 * Temperature Measuring gun;  1 * User Manual
