Advantages
1. Precise Multi-Parameter Control: The chamber allows simultaneous control of temperature (+10 ℃ to +90 ℃), humidity (30 %–98 % RH), and SO₂ gas concentration (25 ± 5 ppm). Integrated PID sensors and real-time monitoring ensure deviations remain within ±0.5 ℃, ±1 % RH, and ±0.1 % FS, providing accurate, repeatable testing conditions for coatings, metals, and plastics.
2. Flexible Test Duration and Protocols: Users can run short-term or extended corrosion tests ranging from 4 to 21 days, with up to 120 programmable profiles and 100-step sequences. Preloaded programs allow quick test setup, while custom sequences support complex industrial standards testing, reducing operator time and increasing lab efficiency.
3. Robust Construction for Harsh Conditions: The workroom is made of glass-fiber reinforced plastics resistant to SO₂, salt, and high humidity, while the exterior A3 steel frame with electrostatic coating ensures long-term durability. Pneumatic seals and double-sealed doors maintain integrity during continuous operation, protecting both the chamber and the laboratory environment.
4. Comprehensive Safety Features: Equipped with dry-combustion protection, over-temperature and over-current shutdown, water shortage sensors, and a fail-safe electromagnetic door lock, the chamber ensures safe operation under extreme corrosive environments, minimizing risk to personnel and samples.
5. Efficient Salt and Gas Delivery Systems: The adjustable spray tower, quartz nozzles, and brine stirring system maintain uniform salt fog deposition at 1–2 ml/80 cm²·h. The integrated SO₂ exhaust device safely neutralizes emissions, while the centrifugal fan ensures even circulation, guaranteeing consistent exposure across all samples.
