1The measurement method is ultra long distance non contact measurement, which reasonably guarantees individual safety. 2Infrared thermometer has the unit switching function, so that you can easily transfer between and units, which is easy to use. 3With low battery indicator and automatic shutdown function, the battery life of the temperature meter can be extended. 4Adjustable emissivity (distance: object distance equal to 12:1) improves the measurement accuracy of different surface types, and has a large highprecision temperature measurement range. 5Suitable for measuring pool temperature, food temperature, car seat temperature, wooden floor temperature, car tire temperature, refrigerator temperature, etc. Item Type: Infrared ThermometerModel: GT950 Material: ABS Battery: 1 x 9V 6F22 (Battery Not Included) Uses: pool temperature measurement, food temperature measurement, car seat temperature measurement, wooden floor temperature measurement, car tire temperature test, refrigerator temperature test, water temperature measurement Temperature Range -50~950(-58~1742) Accuracy 0~950(32~1742): 1.5(2.7)or 1.5% -50~0(-58~32): 3(5) Resolution 0.1or 0.1 Repeatability 1% reading or 1 Response Time 500mSec, 95% Response Response Wavelength 8~14um Emissivity 0.10~1.00 Adjustable (Default 0.95) Object Distance Ratio 12:1 Temperature Operating Range 0~40 (32~104) Relative Humidity 10%RH~95%RH Non Condensing, Until 30 (86) Storage Temperature -20~60(-4~140)1 x Infrared Thermometer (Battery Not Included) 1 x Manual 1 x Portable Cloth Bag To avoid possible harm to the user, please follow the following guidelines:1. When using this machine, please do not aim the laser at eye traces but indirectly shoot it to the eyes through the reflective surface.2. This instrument cannot measure through transparent surfaces such as glass/plastic, etc., otherwise the value measured by this instrument will be the surface temperature of the transparent object.3. Steam/dust/smoke or other particles will form obstacles to the instrument lens and affect the accuracy of the measurement.To avoid damage to the thermometer or the device under test, please protect them from the following influences:1. EMF (Electric Phosphorus Field) thermal shock caused by arc welding machines and induction heaters (caused by large or sudden changes in ambient temperature).2. Wait 30 minutes for the thermometer to reach a stable state before use.3. Do not put the thermometer close to or on high temperature objects.4. This model is an industrial thermometer, not suitable for humans.
