Product Overview
ALP Technology's Salt Spray Test Chamber is a specialized corrosion testing system designed to evaluate the corrosion resistance of materials, coatings, and surface treatments. This salt spray test chamber creates a controlled saline mist environment to accelerate the corrosion process, allowing manufacturers to assess product durability under harsh conditions. The salt spray test chamber is widely used across automotive, aerospace, electronics, marine, and metal finishing industries for quality control, material selection, and compliance testing. By exposing test specimens to a continuous or intermittent salt fog, the chamber helps manufacturers identify coating weaknesses, verify surface treatment effectiveness, and ensure product reliability in corrosive environments.
Product Features
ALP's Salt Spray Test Chamber is engineered with corrosion-resistant materials and precision control features for reliable, accurate testing:
- Corrosion-Resistant Construction: The chamber is constructed from high-quality PVC or glass fiber reinforced plastics, ensuring the equipment itself does not degrade during long-term operation. The inner and outer shells are corrosion-resistant, shock-resistant, and easy to clean with no leakage.
- Precision Temperature Control: Features PID programmable control with a PT100 sensor, providing temperature stability of ±0.5°C and deviation of ±2.0°C. The chamber maintains a working room temperature range from ambient +5°C to +55°C (or higher for composite models).
- Advanced Spray System: Uses an atomizer tower and quartz spray nozzles that are corrosion-resistant and clog-resistant, delivering uniform salt fog distribution. Salt spray deposition is maintained at 1 to 2 ml/80 cm²·h per industry standards.
- Saturated Air Preheating System: A saturated air barrel (typically 31L) preheats and humidifies compressed air before atomization, ensuring stable and consistent spray conditions.
- Flexible Test Modes: Supports both continuous and periodic spray operation, accommodating various test requirements and standards .
- User-Friendly Features: Includes a transparent observation window, pneumatic cover opening, round bar and V-shaped groove sample holders, and adjustable castors with brakes for easy mobility.
- Comprehensive Safety Protections: Equipped with over-temperature protection, over-current protection, water shortage protection, humidifier dry-combustion protection, and earth leakage protection.

FAQ
Q1: What types of products can be tested in a salt spray test chamber?
A: This chamber is used to test metals, coated surfaces, painted parts, electroplated components, anodized materials, and alloys to determine their corrosion resistance. Common applications include automotive components, electronic enclosures, aerospace parts, and marine hardware.
Q2: What is the typical salt solution used?
A: A precise 5% sodium chloride (NaCl) solution prepared with deionized water is typically used. The solution should be prepared using a precision balance and verified with a densitometer for accuracy.
Q3: How do I prevent nozzle clogging?
A: Use pure water for both the saturated barrel and salt solution. After long-term use, remove the nozzle, clean it, and reinstall. Each chamber typically includes a spare nozzle for replacement.
Q4: Can ALP customize the chamber size or features?
A: Yes. ALP's greatest advantage is the ability to customize a variety of non-standard test chambers according to customer requirements, including dimensions and optional features.
Q5: What is the difference between neutral salt spray and cyclic salt spray testing?
A: Neutral salt spray testing (e.g., ASTM B117, ISO 9227) maintains constant temperature and humidity. Cyclic salt spray testing (e.g., IEC 60068-2-52) alternates between salt spray and dry/ humidity conditions, more closely simulating real-world environmental cycles.
