Feature: 1. The thermometer can be easily converted between ℃ and ℉ units to meet your different needs. 2. With low battery indicator and automatic shutdown function, it can ensure battery life and can be used with confidence. 3. The object distance ratio of the thermometer is 12:1, and the adjustable emissivity improves the measurement accuracy. 4. The product is made of high quality ABS material, easy to carry, large temperature measurement range, accurate measurement results. 5. This infrared thermometer is widely used in many situations, such as pools, food, wooden floors, car tires, refrigerators, industry, etc. Specification: Item Type: Infrared Thermometer Model: WT323A Material: ABS Battery: 2 x 1.5V AAA (Battery Not Included) Application: Pool temperature measurement, food temperature measurement, car seat temperature measurement, wooden floor temperature measurement, car tire temperature test, refrigerator temperature test, water temperature measurement LCD Color LCD Temperature Measurement Range -50℃~650℃ (-58℉~1202℉) Temperature Display Accuracy 0.1℃ Temperature Measurement Error -50℃~0℃ (-58℉~32℉): ±3℃ (±5℉) 0℃~650℃ (32℉~1202℉): ±1.5% or 1.5℃ (±2.7℉) Repeatability 1% or 1℃ Response Time 0.5s, 95% response Emissivity 0.10~1.00 adjustable (0.95 preset) D:S 12:1 Response Wavelength 5um~14um LaserCircle spot Flashlight Ultraviolet light Working Temperature 0℃~40℃ (32℉~104℉) Relative Working Environment Humidity 10%RH~90%RH Storage Temperature -10℃~60℃ (14℉~140℉) . Package List: 1 x Thermometer (Battery Not Included) 1 x Manual Note: 1. When using this machine, please do not aim the laser at the eye trace, but indirectly shoot to the eye through the reflective surface2. This instrument cannot measure through transparent surfaces such as glass/plastic3.Wait, otherwise the value measured by this instrument will be the surface temperature of the transparent object4.Steam, dust, smoke or other particles will form an obstacle to the instrument lens and affect the accuracy of the measurement5. In order to avoid damage to the thermometer or the equipment under test, please protect them from the following influences: EMF (Electric Magnetic Field) generated by arc welding machines and induction heaters, thermal shock (due to large or sudden environmental temperature Change caused)6. Wait 30 minutes for the thermometer to arrive a stable state before use7. Do not put the thermometer close to or on high temperature objects8. This model is an industrial thermometer, not suitable for human body
