Product DescriptionSO2 Corrosion Test Chamber - Precision Environmental Test Equipment for Accelerated Corrosion TestingThe SO2 Corrosion Test Chamber is a specialized environmental test device designed to simulate and accelerate the corrosive effects of sulfur dioxide (SO2) gas on materials and products under precisely controlled laboratory conditions. This essential equipment introduces SO2 gas into a sealed workspace and meticulously regulates its concentration (1-30 ppm), temperature (15°C to 80°C), and humidity (30% to 98% RH). By creating these harsh, accelerated environments, it rapidly replicates the degradation caused by industrial atmospheres, exhaust fumes, or polluted environments that materials might encounter over years in the real world. This allows for the efficient assessment of material corrosion resistance, protective coating quality, and product durability, providing critical data for R&D, quality control, and compliance verification.Compliant Standards DIN 50018: Corrosion Testing Standards DIN 50900: Terminology and General Concepts of Metal Corrosion DIN 53210: Rusting Degree Designation of Paint Surfaces ISO 6988: Sulfur Dioxide Test with Moisture Condensation IEC 60068-2-42 & IEC 60068-2-43: Environmental Testing for Contacts and Connections IEC 60079-1:2014 (GB/T5135.3): Explosive Atmospheres Equipment Protection ISO 22479-2019: Sulfur Dioxide Test in Humid AtmosphereKey Applications Material & Coating Evaluation: Test the corrosion resistance of base metals and their protective layers (paints, platings, coatings). Electronics Reliability: Assess the susceptibility of electronic components, PCBs, and connectors to SO2-induced corrosion and failure. Automotive & Aerospace: Evaluate parts and assemblies exposed to industrial exhaust or sulfur-containing atmospheres. Industrial Product Testing: Determine the SO2 corrosion resistance of valves, fasteners, pipes, and other mechanical components. Quality Control & R&D: Compare manufacturing processes and develop new corrosion-resistant materials and finishes. Compliance Verification: Test products against international corrosion standards for market access.Product Features & Advantages1. Precise Environmental Simulation: Advanced microcomputer controller ensures accurate and stable regulation of SO2 concentration (1-30 ppm), temperature (15°C to 80°C), and humidity (30% to 98% RH), enabling reliable accelerated testing.2. Robust & Corrosion-Resistant Construction: Chamber interior made from seamless, pressed anti-corrosion PVC board, guaranteeing long-term durability, leak-proof integrity, and resistance to the test environment itself.3. Enhanced Operator & Environmental Safety: Integrated toxic gas handling system includes dedicated SO2 tank, flow meter, exhaust pipe, drain pipe, and comprehensive safety alarms/protections (e.g., gas leak detection). Double air filters neutralize exhaust gases, preventing environmental pollution.4. Real-Time Observation: Large, transparent observation window allows for visual monitoring of test specimens throughout the exposure period without compromising the test environment.5. Intuitive User Interface: Programmable color LCD touch screen controller simplifies operation, complex test cycle programming, and data logging. Utilizes high-precision PT-100 (Class A) sensors for reliable measurements.6. Controlled Saturated Air System: Features an independent temperature control and display unit for the saturated barrel, utilizing reliable dry-wet bulb humidity sensing technology.7. Flexible Configuration: Available in multiple standard sizes (Reach-in, Walk-in) to suit different testing volumes and fully customizable designs to meet unique test requirements or space constraints.SpecificationModelBND-SDTCInternal Dimensions1600 x 1000 x 500 mmExternal Dimensions2700 x 1300 x 1400 mmTemperature RangeRT +10℃ ~ 60℃Relative Humidity85% ~ 100% R.HTemperature Uniformity± 1.0℃Temperature Fluctuation± 0.5℃Gas Concentration0.05 ~ 1% (volume percentage)Inlet MethodCylinder type, fixed gas methodExhaust InterfaceΦ63 mmExhaust CompositionWeakly alkaline high humidity gas, non-toxic and harmless (after exhaust treatment)Power3.5 KWVoltageAC 220V / 50HZ
