Salzsprühnebel-Testkammer

The DHT® Salt Spray Test Chamber is an advanced corrosion testing solution engineered for accelerated evaluation of material durability, surface coatings, and anti-corrosion treatments under simulated saline environments. Designed for demanding R&D, quality assurance, and compliance testing, it precisely replicates neutral salt spray (NSS), acetic acid salt spray (AASS), and copper-accelerated acetic acid salt spray (CASS) conditions in strict accordance 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.

Vorteile

Precision-Crafted for Repeatable Testing:Equipped with a microprocessor-controlled system and high-accuracy sensors, the chamber ensures uniform fog distribution and stable internal temperatures throughout extended test durations.

Robust, Corrosion-Proof Construction:The inner tank and fog delivery system are manufactured from high-performance engineering plastics (e.g., P.V.C. or PP), ensuring resistance to long-term chemical exposure and operational durability in corrosive test environments.

Versatile Testing Modes & Global Standards Compliance:Supports NSS, AASS, and custom protocols. Fully complies with global testing standards—ASTM B117, ISO 9227, and others—making it ideal for pre-certification, failure analysis, and long-term durability studies.

Intelligent PLC Control & Data Logging:Featuring a touchscreen uPLC control system, users can easily program complex test sequences, monitor real-time chamber conditions, and export test data for documentation and traceability.

Modular & Scalable Design:Available in multiple sizes to accommodate small components, coated fasteners, or large panels. Optional features like automatic water replenishment and remote monitoring further enhance usability in high-throughput labs.
