Salt fog (salt spray) chambers are indispensable for evaluating the corrosion resistance of materials and coatings in automotive, aerospace, electronics, hardware, coatings and defense industries.

The HAST test chamber simulates extreme environments to accelerate the reliability and durability testing of electronic, automotive, and other products. It helps enterprises identify potential problems in advance and enhance their market competitiveness.

Cold and hot shock test chambers utilize high-temperature and low-temperature zones during testing. In the testing process, two-box models involve placing the test product in high and low-temperature zones for cyclic exposure, while three-box models involve blowing high- and low-temperature gases onto the product alternately.

A constant temperature and humidity test chamber consists of multiple components, and any malfunction can disrupt testing. Previously, we discussed troubleshooting methods for other issues. Today, we focus on expansion valve failures.

When a cold and hot shock test chamber, which has been running smoothly, suddenly stops cooling, what could be the reason?
