Salt Spray Cabinet Features and Benefits
1. Accelerated and Controlled Corrosion Testing
The chamber simulates a marine salt spray environment to accelerate material corrosion, significantly shortening test cycles and improving efficiency. The salt fog is generated under stable conditions with 83 kPa spray pressure and a deposition rate of 1–2 mL/80 cm²·h, fully compliant with ASTM B117 and ISO 9227 standards, ensuring reproducible results across batches.
2. Stable Temperature and Humidity with Precise pH Control
Equipped with PT-100 Class A sensors (±0.001 °C resolution), the chamber maintains temperature within ±0.5 °C and humidity between 95%–98% RH. Salt solution pH is stabilized for NSS (6.5–7.2) and AASS/CASS (3.1–3.3) tests, ensuring highly accurate and repeatable corrosion conditions.
3. Flexible Sample Capacity and Placement
Standard V-groove and round-rod holders allow adjustable sample angles (15°–30°) to prevent shielding effects, enabling multiple samples to be tested simultaneously. The chamber supports a range of model volumes, from small R&D batches to high-throughput production validation.
4. Durable Construction for Long-Term Testing
Designed to withstand continuous exposure to salt fog, high temperature, and humidity, the interior remains structurally stable over extended test periods. The inverted-V lid prevents condensate drip, maintaining test validity and reducing maintenance needs.
5. Efficient and Safe Operation
Automated water replenishment, dry-burn protection, and a programmable controller with real-time logging allow safe, unattended operation. Test programs can be fully customized, with continuous or cyclic spray options, while monitoring and alerts ensure safe, reliable operation.

FAQ – Salt Spray Cabinet
Q1: How to prevent salt spray leakage?
A1: To prevent salt spray leakage, our cabinet is made of one-piece fiberglass reinforced plastic, which is sturdy and corrosion-resistant. Additionally, the cabinet features a water-tight sealing trough. Simply fill the trough with water during testing to effectively prevent salt spray from escaping, ensuring a safe and clean testing environment.
Q2: Does the salt spray chamber have an automatic water inlet?
A2: Yes, the cabinet is equipped with an automatic water inlet, which replenishes water as needed based on usage. This ensures stable and continuous operation without frequent manual intervention.
Q3: Can the manual transparent cover be replaced with a pneumatic fiberglass cover?
A3: Yes. The manual transparent cover can be upgraded to a pneumatic fiberglass cover. LIB Industry can customize all non-standard options to meet specific testing requirements.
