Black standard thermometer of xenon lamp weathering resistance test box: This thermometer is made of flat stainless steel with a length of 70mm, a width of 40mm and a thickness of 1mm. The side of the flat panel facing the light source is coated with an anti-aging black flat coating. The coated blackboard absorbs at least 95% of the total incident light within 2500nm, and then uses a platinum resistance sensor to measure the temperature of the plate. When the black standard thermometer and the sample are irradiated at the same position of the sample holder, the black standard temperature is similar to the temperature of the dark sample with poor thermal conductivity.

In order to determine the temperature range of the sample surface and better control the irradiance and test conditions of the equipment, the manufacturer recommends the use of a white standard thermometer in addition to a black standard thermometer. The white standard thermometer has the same design as the black standard thermometer. It replaces the black flat coating with an aging-resistant white coating. The absorption of the white coating is at least 90% lower than that of the black flat coating in the range of 300 ~ 1000nm, and at least 60% in the range of 1000 ~ 2500nm.

Xenon lamp weathering test chamber can reproduce the damage caused by sunlight, rain and dew in a few days or weeks. The equipment test sample holder rotates around the light source at a speed of 1r / min. A black standard thermometer is installed on the sample holder. The control black standard thermometer uses wireless transmission technology to effectively improve the control accuracy.
