Introduction
Product Introduction & Applications
The Salt Spray Testing Machine is an essential environmental testing instrument for evaluating corrosion resistance of materials and coatings. Widely used in machinery, national defense, electronics, light industry, and instrumentation, it simulates harsh saline environments to test product adaptability and durability.
This chamber can perform:
Neutral Salt Spray Tests (NSS) in accordance with GB/T 2423.17.
Acetic Acid Salt Spray Tests (CASS) to simulate aggressive corrosive environments.
Its design ensures accurate control of temperature, spray rate, and deposition uniformity, enabling reliable assessment of material performance under corrosive conditions.

Usage Notes
Fill the solution tank with the correct concentration of salt solution according to the test standard.
Ensure proper leveling of the chamber to maintain uniform deposition.
Regularly clean the nozzles to prevent clogging and maintain spray accuracy.
Avoid opening the chamber during operation to prevent temperature fluctuations and test interruption.
Periodically check the PID temperature controller for calibration and accuracy.
FAQ
What types of tests can this machine perform?
