Application Industries
Shipbuilding and Marine Engineering
Tests the corrosion protection capability of ship hull coatings and deck equipment in simulated high-salt marine environments.
Bridge Steel Structure Corrosion Protectio
Evaluates the corrosion rate and coating durability of bridge cables and steel components under alternating salt spray and humid conditions.
Outdoor Power Facilities
Validates the electrochemical corrosion and insulation performance changes of transmission towers and substation fittings in coastal salt spray climates.


Product Features
Composite Corrosion Environment Simulation
Supports combined cycles of multiple modes, including neutral salt spray, acid salt spray, copper-accelerated acetic acid salt spray (CASS), as well as drying and humidity.
Large-Space Uniform Spraying
Utilizes a tower spray system and multi-nozzle layout to ensure salt spray settling uniformity in the chamber reaches ±1.0 ml/80 cm²·h.
Intelligent Anti-Crystallization Design
Equipped with automatic flushing of spray pipelines and constant-level control of the saturator bucket to prevent salt crystallization and blockages, enhancing long-term operational stability.





Sales Q&A
Q: How are salt spray concentration and pH value precisely controlled?
A: A high-precision salt solution mixing system and real-time pH monitoring module are used, with concentration error ≤±0.5% and pH fluctuation range ≤±0.2.
Q: Does it support combined testing with other environmental factors, such as ultraviolet light?
A: It can be expanded to connect with modules such as UV and ozone, enabling multi-factor corrosion testing combining salt spray, light, and ozone.
Q: How is wastewater handled after long-term operation?
A: The equipment is equipped with neutralization treatment and wastewater recovery devices, adjusting wastewater pH to 6–8 before centralized discharge, complying with environmental standards.
