The salt spray test box uses salt spray corrosion to detect the reliability of the respective corrosion resistance of the tested samples. Salt spray refers to a dispersion system composed of salty tiny droplets in the atmosphere. It is one of the three-prevention series of artificial environments. Many enterprise products need to simulate the destructive effects of the ocean surrounding climate on the products, so the salt spray test chamber is therefore invented.

The instrument has a high degree of intelligence, multiple PID calculations and fuzzy control, fast tuning, and achieve smoother control output and higher control accuracy.
