Features

Composite cyclic design combining salt spray and wet-heat environment for realistic corrosion simulation.

Programmable cycles allow customization of spray time, static time, and temperature-humidity conditions.

SUS304 stainless steel inner chamber ensures corrosion resistance and easy cleaning.

Precise control of solution concentration and pH, with uniform salt spray distribution (deviation ≤±1%).

High-precision temperature and humidity control: temperature fluctuation ≤±1℃, humidity deviation ±2–3%.

Integrated PID intelligent control with user-friendly interface for programmable cycles.

Eco-friendly design with rapid heating for spray and pressure tank systems.

High power (26 kW) ensures continuous, efficient operation.
