Product Introduction It's safely and quickly used for measuring the temperature of the object's surface without contact. The unit is equipped with a laser,which is used for aiming, consists of optics,temperature sensor, signal amplifier,processing circuit and LCD display. Principle All objects whose temperature is higher than absolute zero emits infrared radiation energy proportionally. The optics collected the infrared energy emitted by object and focus ontothe sensor. Then the sensor translates the energy into an electricity signal. This signal willbe turned out to be digital shown on the LCD after the signal amplifier and processing circuit. Features: 1) Use a HEIMANN infrared temperature probe, with high precision and stable performance. 2) High measurement temperature (settable), sound prompt function 3) Backlight (LED) display 4) °C/°F selection 5) Emissivity: 0.1~1.00 (adjustable) 6) Laser target pointer 7) Auto power shut off (Battery saving) 8) Compact size, Proper structure and easy operation. Main Technical Indexes 1) Normal working conditions: a. environment temperature range : 10°C ~ 30°C, storage temperature range: -10°C ~-40°C b. relative humidity: no more than 90% c.
