Applications
The Photovoltaic Acid Mist Test Chamber is a specialized device designed to simulate coastal environments with high salt fog concentrations, enabling the evaluation of photovoltaic modules' corrosion resistance. Its core function involves precisely controlling salt mist concentration, temperature, and humidity to accelerate material aging processes, thereby assessing product lifespan under harsh environmental conditions.
Standards
IEC 60068-2-42. IEC 60068-2-43. IEC 60068-2-60
GB/T 10125 Artificial Atmosphere Corrosion Tests - Salt Spray Test
ISO 9227 Corrosion Tests under Artificial Atmospheres - Salt Spray Test
ASTM B117 Laboratory Simulation of Salt Spray Environments (e.g., Marine or Humid Climates)
Features
1.Multi-Gas Synergy: Unlike standard salt spray boxes, this system allows you to introduce $H_2S$, $NO_2$, and $Cl_2$ simultaneously, providing a more realistic "industrial-marine" complex environment.
2.Large-Format Throughput: The internal architecture is optimized to hold six full-sized PV modules, ensuring your testing throughput meets industrial R&D demands.
3.High-Precision Flow Control: Equipped with advanced flowmeters (accuracy $<pm 1%$), giving you total confidence in the repeatability of gas concentration levels.
4.Corrosion-Resistant Build: The chamber interior is constructed from reinforced, high-temperature resistant plastics or specialized alloys to withstand acidic and saline exposure without self-corrosion.
5.Automated Cycle Management: You can program complex sequences of spraying, drying, and humidifying to simulate changing weather patterns over a single test period.

Test Procedures
1.Preparation
Sample Preparation: Clean the samples and secure them on the sample rack, ensuring they do not touch each other.
Solution Preparation: Prepare a 5% NaCl solution (pH 6.5-7.2) according to the standard.
2.Power-Up and Parameter Settings
Power Connection: Connect the power supply and turn on the main switch.
Parameter Settings:
Temperature: 35°C ± 2°C (salt spray phase) or 40–60°C (drying phase).
Humidity: 85% RH ±5%.
Test Cycle: Set the number of cycles and duration for spraying, drying, and humidification.
3. Test Operation
Start Test: After confirming parameters are correct, press the “Start” button.
Spray Inspection: Once temperature is reached, the spray system automatically activates. Observe spray uniformity.
Operational Monitoring:
Daily checks of temperature and spray volume.
Periodically replenish salt solution (recommended every 24 hours).
Monitor pressure gauge (0.7-1.5 kgf/cm²).
4. Test Conclusion
Shutdown Procedure: Turn off spray switch, allow temperature to drop below 40°C before disconnecting power.
Sample Removal: Retrieve specimens for corrosion assessment.
