Weanas (TM) Infrared IR Laser Thermometer Temperature Sensor Non-Contact Digital LCD Display LED Backlight Laser Pointer Measurement Range Between -50 °C and 380 °C (Between -58 °F and 716 °F)
* The Optics collected the infrared energy emitted by object and focus onto 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.Specification:Measurement Range: Between -50 C and 380 C (Between -58 F and 716 F )Accuracy:  1.5% or 1.5CRepeatability:  1% or 1CResolution: 0.1C or 0.1FResponse Time: 500mSecDistance to Spot Size: 12:1Spectral Response: 8 - 14umStorage Temperature: Between -20C and 60C (Between -4 F and 140 F )Operating Temperature: Between 0C and 40C (Between 32 F and 104 F )Operating Humidity: 10 - 95% RHnon-condensing, up to 30C (86F )Power: DC 9V battery (included)Package Included:1 x IR Thermometer1 x User manual1 x DC 9V battery
