Composite Salt Spray Test Chamber — SSTC / W-STH Series

The TestEQ composite salt spray test chamber runs salt spray, high-humidity, drying and optional temperature phases in one programmable cabinet, so corrosion is driven through realistic wet-dry and salt-fog cycles rather than continuous spray alone. Cabinet models cover small to medium samples; walk-in models take oversized assemblies such as vehicle parts and battery enclosures.

Applications

  • Automotive parts, fasteners, chassis components and coatings
  • EV battery enclosures, connectors and terminals
  • Aerospace structures and surface treatments
  • Marine equipment and offshore structures
  • Paints, coatings and metal finishing
  • Electronics, connectors and plating

Configuration and features

  • Cyclic corrosion: salt spray, humidity, drying and optional temperature variation in programmed multi-stage profiles.
  • Test modes ACSS, SOAK, DRYAIR, HUMI and ROOMAIR on walk-in models.
  • Continuous or programmable spray.
  • Uniform salt fog distribution with a precision nozzle system.
  • Corrosion-resistant structure for long-duration testing.
  • Saline concentration 5 % NaCl, or 0.26 g CuCl₂·2H₂O added per litre of 5 % NaCl for CASS.
  • Compressed air pressure 1.0 to 6.0 kgf.
  • Spray volume 1.0–2.0 ml/80 cm²/h, averaged over at least 16 hours of working time.
  • Optional SO₂ corrosion module, temperature cycling integration, remote monitoring and data logging, and acid-resistant materials for CASS.
