Feature:1. Convenient unit conversion, it can easily convert between / units, allowing you to record and measure test values more conveniently.2. Low battery indicator, it can promptly remind when the battery is low, and automatically shut down after a period of inactivity to ensure battery life.3. Adjustable emissivity, it can be adjusted according to different situations, the object to distance ratio is 12:1, which improves the measurement accuracy of different surface types.4. Large temperature measurement range, it has a wide range of temperature ranges, can perform non contact measurement at long distances, and can protect people from harm.5. Wide application range, it is suitable for pool temperature measurement, food temperature measurement, car seat temperature measurement, wooden floor temperature measurement, automobile tire temperature test, refrigerator temperature test, water temperature measurement.Specification:Item Type: Infrared ThermometerModel: 900Material: ABSBattery: 1x9V 6F22 (Battery Not Included)Uses: It is suitable for pool temperature measurement, food temperature measurement, car seat temperature measurement, wooden floor temperature measurement, automobile tire temperature test, refrigerator temperature test, and water temperature measurement.Temperature Range-50~950 (-58~1742)Accuracy0~950 (32~1742): 1.5 (2.7) Or 1.5%-50~0(-58~32): 3(5)Resolution0.1C Or 0.1FRepeatability1% Of Reading Or 1Response Time500mSec, 95% ResponseResponse Wavelength8~14umEmissivity0.10~1.00 Adjustable (Default 0.95)Object Distance Ratio12:01Temperature Operating Range0~40 (32~104)Relative Humidity10%RH~95%RH Non-Condensing, Until 30 (86)Storage Temperature-20~60 (-4~140).Package List:1 x Infrared Thermometer (Battery Not Included)1 x Manual1 x Tool BoxNote:1. Warning:To avoid possible harm to the user, please follow the following guidelines:Please do not aim the red light at the eyes or indirectly through the reflective surface to the eyes when using this machine.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;Steam/dust/smoke or other particles will form obstacles to the instrument lens and affect the accuracy of the measurement.2. Note:To avoid damage to the thermometer or the device under test, please protect them from the following influences:1. EMF (Electric Phosphorus Field) produced by arc welding machines and induction heaters.2. Thermal shock (due to large or sudden changes in ambient temperature).3. Wait 30 minutes for the thermometer to reach a stable state before use.4. Do not put the thermometer close to or on high temperature objects.5. This model is an industrial thermometer and is not suitable for humans.
