This infrared thermometer is used for measuring the temperature of the object's surface、 which is applicable for various hot、 hazardous or hard-to-touch objects without contact safely and quickly. This unit consist of Optics、 Temperature Sensor、 Singal amplifier、 Processing circuit and LCD Display. The Optics collected the infrared energy emitted by object and focus on to the Sensor. Then the Sensor translates the energy into an electricity signal. This signal will be turned out to be digital shown on the LCD after the signal amplifier and processing circuit. Features:1. Precise non-contact thermometer、 highly accurate and reliable.2. Compact size、 one-handed design for simple and convenient operation.3. Simply point to an object and read its temperature.4. LED back light design for operation under poor illumination5. ¡ãC / ¡ãF selection and laser traget pointer ON /OFF selection.6. Supports MAX / MIN / AVG / DIF reading.7. Supports high / low temperature alarm setup.8. Laser pointer for accurate target aiming.9. With data store recall function and data hold function10. Laser on/off switch、 Auto power off & temperature data hold.11. Applications: hot water pipes、 hot engine parts、 cooking surfaces、 hot tubes insulation、 electrical connection、 ballasts in electric lights、 electric motors、 bearings、 wine coolers hot asphalt、 swimming pools、 fish tanks、 hot cold food products、 heating air conditioning、 etcSpecifications: Temperature range -50 to 700¡æ (-58 to 1292 ¡ãF)Accuracy 0¡«700¡æ£º¡À1.5% or ¡À1.5¡æ  -50¡«0¡æ: ¡À3¡æResolution 0.1¡æ or 0.1¡ãF Repeatability1% of reading or 1¡æSpectral response  8-14 umEmissivity 0.95 presetDistance to spot size 12 : 1Operating temperature 0 ~ 40¡æ (32 ~ 104 ¡ãF)Operating humidity 10 ~ 95 % RH non-condsing、 up to 30¡æ(86¡ãF)Storage temperature 0 ~ 40¡æ (32 ~ 104 ¡ãF)Power supply 9V Alkaline or NiCd Battery (NOT Included)Dimensions Approx. 175 * 100 * 50mm                                               Approximate Emissivity Material Emissivity Material Emissivity Material Emissivityaluminum 0.30 freeze food 0.90 skin 0.98asbestos 0.95 hot food 0.93 plastic 0.95asphalt 0.95 glass 0.85 rubber 0.95brass 0.50 ice 0.98 snow 0、90brick 0.9 iron 0.7 stainless steel 0、80carbon 0.95 lead 0.50 paper 0.95concrete 0.95 oil 0.94 water 0.93copper 0.95 paint 0.93 wood 0.94 Package include1 x Infrared Thermometer1 x User Manual
