1. Controlled and Uniform Salt Fog Output: The test chamber maintains a constant spray pressure of 83 kPa, achieving a salt fog deposition rate of 1–2 mL/80 cm²·h, fully aligned with ASTM B117 and ISO 9227 requirements. The optimized spray tower and quartz nozzles ensure uniform fog distribution across the entire test space, reducing deviation between sample positions and improving result consistency.
2. High-Accuracy Temperature and pH Stability: Test temperature is controlled at 35 ± 2 °C, with a fluctuation of ≤ ± 0.5 °C during continuous operation. The system supports salt solution pH control of 6.5–7.2 (NSS) and 3.1–3.3 (AASS/CASS). Integrated PT-100 Class A sensors (0.001 °C resolution) provide precise monitoring, ensuring stable and repeatable corrosion conditions throughout long-term tests.
3. Flexible Sample Capacity with Defined Load Performance: Standard V-groove and round-rod sample holders support adjustable specimen angles from 15° to 30°, allowing multiple samples to be tested simultaneously without shielding effects. The chamber accommodates different model volumes (e.g. 150 L to over 2000 L), enabling both small-batch R&D testing and high-throughput production validation.
4. Durable Construction for Long-Duration Corrosion Testing: The chamber interior is designed for continuous exposure to 5 % NaCl solution at elevated temperature and humidity without structural degradation. The inverted-V transparent lid effectively prevents condensate drip onto specimens, maintaining test validity over hundreds to thousands of operating hours and reducing maintenance intervention.
5. Efficient Operation with Built-In Safety Thresholds: Automated water replenishment and dry-burn protection stop operation when water levels fall below safe limits, preventing heater damage. The programmable controller stores up to 120 programs with 100 steps each, supports continuous or cyclic spraying, and logs temperature, spray duration, and deposition data in real time for traceable, audit-ready reports.

1. Ensure the test chamber is level and connected to a stable power and water supply.
2. Fill the salt solution tank according to the desired test method (NSS, AASS, or CASS) and set the solution concentration and pH within standard limits.
3. Use the touchscreen controller to program test parameters, including temperature, spray pressure, deposition rate, and test duration.
4. Place samples securely on the adjustable V-groove or round-rod holders, and close the inverted-V lid.
5. Start the test. The system automatically monitors temperature, spray, and solution levels, providing real-time alerts and logging all data for traceability.
6. After completion, safely remove samples and clean the chamber for the next test cycle.
1. Salt Spray and Immersion Testing for corrosion testing under different conditions.
2. Walk-In Salt Spray Testing for large solar panels and other oversized products.
3. Flexible Customization of test chamber size, test functions, and other features to meet your needs.
