FEATURES: 100% brand new and high quality. Used for measuring temperature of an object's surface, which is applicable for various hot, hazardous of hard-to-reach objects without contact safely and quickly Consist of Optics, Temperature sensor signal amplifier, Processing circuit and LCD display The optics collects the infrared energy emitted by object and focuses onto the sensor. Then the sensor translates the energy into an electricity signal. This signal will be digitally shown on the LCD after the signal amplifier and processing circuit. Accurate targeting with laser pointer for simple one-handed operation. Low-light LCD and back light feature. It has low battery indicator and 7-second inactivity shutdown function. Temperature °C/°F switchable High & Low temperature alarm SPECIFICATIONS: Temperature range: -50~550℃ (-58~1022℉) Accuracy: 0~550℃(32~1022℉): ±1.5℃(±2.7℉) or ±1.5% -50~0℃(-58~32℉):±3℃ (±5℉) Whichever is greater Repeatability: 1° C or 1% of reading Resolution: 0.1° C or 0.1° F Response time: 500 m/sec at a 95% response time Emissivity: 0.1 to 1.0 (adjustable) Distance to spot ratio: 12:1 Spectral response: 8 to 14 um Power: 1.5V AAA x 2PCS (Not Included) Weight: Approx. 195g / 6.9oz Set Comprise of: 1 x IR Thermometer English Instruction Manual Standard Factory Packaging
