Salt Spray Corrosion Test Chamber

Name: Salt Spray Corrosion Test Chamber
Brand: Xi'an LIB Environmental Simulation Industry

LIB industry salt spray corrosion test chamber accurately reproduces coastal and marine corrosive environments, enabling manufacturers to evaluate the corrosion resistance of materials, surface treatments, and finished products under controlled temperature (ambient to +60 °C) and high humidity conditions (95–98% RH).

By atomizing a NaCl solution into a fine and uniform salt fog with a controlled deposition rate of 1–2 ml / 80 cm²·h, the chamber continuously surrounds test specimens, accelerating corrosion processes and exposing potential failure risks at an early stage of the product lifecycle.

The system supports neutral salt spray (NSS) and continuous corrosion testing, with stable PID-controlled operation and repeatable test conditions. It is fully compliant with major international standards such as ASTM B117 and ISO 9227, and is widely applied in automotive, electronics, hardware, coatings, and military industries for qualification, validation, and comparative testing.

Model: S-150,S-250, S-750, S-010, S-016, S-020 custom internal dimensions and configurations can be provided based on sample size and test requirements.

Standard: ASTM B117, ISO 9227, ASTM G85, D17 2028, SAE J2334, ISO4611, ISO7253, IATF 16949, IEC 60068-2-11, ASTM G85-02e1 Annex A1, DIN 50021, ASTM B368

Salt Spray Corrosion Test Chamber Features and Benefits

1. Excellent Sealing Design – Clean & Stable Test Environment

The water-sealed chamber structure ensures tight sealing between the cover and chamber body, effectively preventing salt fog leakage during long-term testing.
The sealing system supports continuous operation up to 60 °C under 95–98% RH, maintaining stable internal conditions throughout the test cycle.

✔ Stable internal environment for long-duration salt spray tests
✔ Cleaner laboratory space with minimal salt fog escape
✔ Suitable for ASTM B117 and ISO 9227 continuous exposure requirements

2. Precise Control for Repeatable Test Results

The salt spray corrosion test chamber is controlled by a microprocessor-based PID controller, enabling precise and stable regulation of key test parameters:

Temperature range: Ambient ~ +60 °C
Temperature fluctuation: ±0.5 °C
Temperature deviation: ±2.0 °C
Salt fog deposition rate: 1–2 ml / 80 cm²·h
Spray mode: Continuous or periodic

3. Uniform Salt Fog Distribution – Closer to Real Corrosive Environments

The tower spray method, combined with a specially designed anti-crystallization glass nozzle, ensures uniform salt fog distribution throughout the working volume.

✔ Even fog coverage across different sample positions
✔ Stable deposition rate within 1–2 ml / 80 cm²·h
✔ Accurate simulation of marine and industrial corrosive atmospheres
✔ Reduced deviation between parallel test samples

4. Highly Corrosion-Resistant Chamber Body

The entire chamber body is manufactured from glass fiber reinforced plastics (FRP) using one-time integral molding, designed for long-term exposure to high-salinity environments.

✔ Strong corrosion resistance to NaCl solution
✔ Operating temperature resistance up to +60 °C
✔ Reinforced structure for extended service life
✔ Smooth surface for easy cleaning and low maintenance

Configuration of Salt Spray Corrosion Test Chamber

The Salt Spray Corrosion Test Chamber from LIB industry features precise temperature and humidity control, uniform salt fog distribution, adjustable test cycles, and real-time monitoring. It simulates harsh corrosive environments to quickly evaluate material durability, coatings performance, and component lifespan, ensuring accurate, repeatable test results every time.

Workroom	Standard round rod and V-shaped groove design allow test pieces to be freely placed and angled for optimal exposure, ensuring accurate evaluation of corrosion resistance. Customized insert holders are available for irregular samples, providing flexibility for diverse testing needs.
Spray tower	The spray tower has adjustable height and spray volume. Composed of Nozzle: Made of special glass nozzle, no crystal nozzle design. Tower body: the whole molded by high temperature welding, corrosion resistance, easy to clean, no leakage. The spray volume can be freely adjusted in the range of 1-2ml/80cm²·h to meet different standards and test requirements.
Controller	Users can set temperature, humidity, spray duration, and other parameters through the intuitive control system, with real-time monitoring of all data. This ensures consistent test conditions, reduces operator errors, and guarantees reliable, repeatable results.
Salt solution tank	Built-in 30L tank with a brine mixing system (external tank for S-010, S-016, S-020) keeps the solution uniform, maintaining consistent fog density and accurate simulation of corrosive environments, saving time and enhancing test reliability.
Free Industrial Salt	High-purity sodium chloride, dissolved in distilled water to standard concentration (usually 5%), simulates natural corrosive factors like sea breeze, seawater, or industrial atmosphere. LIB industry provides this salt free of charge, reducing operational costs while ensuring consistent, high-quality test results.
