Black standard thermometer for aging test chamber xenon lamp

Test chamber weather resistance xenon lampBlack standard thermometer: This thermometer is made of flat stainless steel with a length of 70 mm, a width of 40 mm and a thickness of 1 mm. The side of the plate facing the light source has an age-resistant 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 board. When the black standard thermometer and the sample are irradiated at the same position of the sample holder, the black standard temperature is close to the temperature of the dark sample with poor thermal conductivity.
To determine the temperature range of the sample surface and better control the irradiance and test conditions of the equipment, the manufacturer recommends using a standard white thermometer in addition to the blacke standard thermometer. The white standard thermometer has the same design as the black standard thermometer, with an aging-resistant white coating instead of a black flat finish. Compared with black flat coating, the absorption of white coating is at least 90% lower in the range of 300~1000nm and at least 60% lower in the range of 1000~2500nm.
Xenon Lamp Weathering Test Chamber can reproduce the damage caused by sunlight, rain and dew in days or weeks. The sample holder of the equipment test rotates around the light source at a speed of 1r/min. A black standard thermometer is installed on the sample holder. The black standard thermometer is controlled by wireless transmission technology, which effectively improves the control accuracy. The gauge has the same design as the standard black thermometer, with an aging-resistant white coating instead of a black flat finish. In comparisonwith black flat coating, the absorption of white coating is at least 90% lower in the range of 300~1000nm, and at least 60% lower in the range of 1000~2500nm.
