Description: This handheld infrared thermometers can detect the surface temperature of non-contact objects, have fast response speed, and have a wide measurement range. They are widely used in petroleum, chemical, railway and other industries, electric power, textiles, plastics, metal processing, Energy saving etc. The emissivity is adjustable. In order to ensure the accuracy of the measurement, it is necessary to define different emissivity according to different measurement targets. For example, when measuring alumina, the emissivity needs to be adjusted to 0.20-0.40. When measuring glass, the emissivity needs to be adjusted to about 0.85. The emissivity of traditional infrared thermometers is usually set to 0.95, which has a significant impact on measurement accuracy. With high and low temperature alarm function. For example, when we check the temperature of a car engine, as long as the high temperature alarm temperature is set, once the measured target exceeds this temperature, the red indicator light on the top of the product will light up. Celsius and Fahrenheit can be switched,high-definition display backlight.
