Step in constant temperature and humidity chamber, also known as high temperature and high humidity test chamber, high and low temperature alternating humidity test chamber, constant temperature and humidity test chamber, high and low temperature test chamber, constant temperature and humidity test machine, high and low temperature humidity and heat cycle test chamber, temperature and humidity test chamber, has the following characteristics:
1. A test chamber capable of simultaneously applying temperature and humidity stress, consisting of a refrigeration system, heating system, humidification system, control system, air circulation system, sensor system, etc; The above systems belong to two major aspects: electrical and mechanical refrigeration.
2. Adopting a balanced temperature and humidity control system (BTHC), the SSR is controlled by P.I.D to ensure that the heating and humidification amount of the system is equal to the heat and humidity loss, ensuring long-term stable operation of the test chamber.
3. It has a large temperature and humidity control range and can provide: constant low temperature test, constant high temperature test, constant humidity and heat test chamber, high temperature and high humidity test, and high low temperature humidity and heat combination cycle test.
4. Suitable for environmental reliability screening and testing in various industries such as plastics, electronic hardware, food, clothing, vehicles, metals, chemical engineering, building materials, instruments, etc; Conduct reliability tests such as temperature and humidity aging tests, hydrolysis and yellowing resistance tests.
5. This equipment is designed and manufactured according to the technical conditions of GB10586-89 humidity and heat test chamber, and complies with GB/T2423.1-93 Test Regulations for Electrical and Electronic Products and Low Temperature Test Methods; GB/T2423.2-89 Test procedures for electrical and electronic products, high temperature test methods; GB/T2423.3-89 Test Procedures for Electrical and Electronic Products, Constant Damp Heat Test Method, and GB/T2423.4-89 Alternating Damp Heat Test
