Constant Temperature Humidity Environmental Climatic Test Chamber

_{The constant temperature and humidity test chamber is used to test various performance indexes of electronic products, materials, electrical engineering, instruments and meters under high and low temperature or humid and hot environments. Why do electronic products need constant temperature and humidity environmental test? With the rapid development of modern industrial technology, the application fields of electronic and electrical products are becoming wider and wider, and the environmental conditions they are subjected to are becoming more and more complex and diverse. Only by reasonably stipulating the environmental conditions of the product and choosing the correct environmental protection measures for the product can the product be protected from damage during storage and transportation, and safe and reliable during use.}

_{Therefore, artificial simulation of electronic and electrical products. Environmental testing is to ensure that it is safe and reliable in all aspects of production, transportation, and use. Performing artificial environmental tests on electronic and electrical products before leaving the factory is an indispensable and important link for quality assurance. Therefore, whether environmental test conditions, test methods, and test equipment comply with standards is of great importance. The constant temperature and humidity test chamber is one of the main tests of the artificial three defenses, and its application is becoming more and more extensive, and it is also being valued by more and more military products, scientific research institutions, universities and other research institutions.}

_{This series of constant temperature and humidity test chambers is suitable for the reliability test of various industrial products. It has the characteristics of temperature control accuracy and wide control range. Its performance indicators comply with GB5170.2.3.5.6-95 "Method for Verification of Basic Parameters of Environmental Test Equipment for Electrical and Electronic Products" Low temperature, high temperature, constant damp heat, alternating damp heat test equipment" requirements.}
