Salt Spray Test Chamber

The DHT® Salt Spray Test Chamber is an advanced solution specifically designed for accelerated corrosion test applications. It enables precise evaluation of material durability, surface coatings, and anti-corrosion treatments under simulated saline environments. Engineered for rigorous R&D, quality assurance, and compliance testing, this chamber accurately replicates neutral salt spray (NSS), acetic acid salt spray (AASS), and copper-accelerated acetic acid salt spray (CASS) conditions, fully complying with ASTM B117, ISO 9227, and GB/T 10125 standards.

Ideal for industries such as automotive, electronics, aerospace, and metal surface treatment, this chamber offers:

  • Tight temperature control (±0.3 °C fluctuation),
  • Uniform atomization of salt fog,
  • Adjustable spray volume and timing,
  • Intuitive touchscreen interface with programmable automation.

The DHT® system enables reliable, repeatable corrosion simulations to uncover rusting, blistering, delamination, or coating failure—critical for certifying product longevity, improving protective technologies, and meeting export/regulatory compliance.
