The temperature and humidity in the high and low temperature laboratory are important factors affecting the performance of the device, which may cause corrosion of mechanical parts, decline of metal mirror, and errors or performance degradation caused by high and low temperature mechanical parts; .
Optical elements such as grating were corroded by constant temperature electron microscope, focusing lens and aluminum at high and low temperature. Stray light and noise caused by insufficient light, or even the equipment stops working, thus affecting the high and low temperatures, so it is necessary to correct it regularly to maintain its service life.
Extended data:
High and low temperature working environment, dust and corrosive gas will also affect the flexibility of mechanical system, reducing the types of limit switches and buttons, and the reliability of optical coupler is one of the reasons for the research of aluminum corrosion.
The temperature is high and the temperature rises quickly, so it is usually best not to add water to avoid affecting the machine. Opening the door of the test chamber during the test will cause the temperature and humidity in the test chamber to fluctuate; If the door is opened many times or for a long time during the test or the test sample emits wet steam, it may cause the heat exchanger of the refrigeration system to freeze and fail to work normally.
