Salt-spray corrosion testing is one of the most frequently used and fastest accelerated methods for evaluating the corrosion resistance of materials and their protective coatings. In a test chamber a salt solution is atomized by compressed air into a uniform fog that is continuously or intermittently sprayed onto specimens in a sealed, temperature- and humidity-controlled space.

Although both thermal-shock and steady-state temperature/humidity tests fall under the umbrella of “weathering verification”, they differ fundamentally in physical modelling, control logic and safety strategy.

What is the purpose of the touchscreen temperature and humidity controller in a high-low temperature alternating humidity test chamber?
