Product Introduction

The sulfur dioxide corrosion chamber is a specially designed corrosion testing device used to simulate the exposure effects of sulfur dioxide (SO₂) gas under controlled environmental conditions. It is used to evaluate the corrosion resistance of materials and their protective coatings in sulfur-polluted environments. This equipment accelerates the corrosion of materials or products by introducing sulfur dioxide gas under specific temperature and relative humidity conditions, thereby reproducing the degree of damage suffered by materials or products over a specific time period.

Both the inner and outer chambers are made of corrosion-resistant, anti-aging, and high-strength polypropylene (PP) reinforced rigid plastic sheets. This material does not react with or absorb sulfur dioxide, therefore it does not affect the accuracy of the test results. The PP plastic sheet has a smooth and flat surface, is resistant to aging and corrosion, and has excellent chemical stability and mechanical properties. The chamber door is made of fully transparent, high-temperature resistant, high-quality tempered glass. The extra-large tempered glass door allows clear observation of the test samples during the test without affecting the accuracy of the results. The transparent tempered glass has good mechanical strength and temperature resistance, while also meeting the requirements for real-time monitoring during the test. The chamber cover and chamber body are sealed with corrosion-resistant silicone rubber to effectively prevent sulfur dioxide gas leakage.

Application areas

It is mainly applicable to the automotive and transportation industry, electronics and electrical industry, connectors and contacts, metal materials and surface treatment industry, coatings and painting industry, aerospace and defense, building materials and building hardware, petrochemical and power industry, rail transportation industry, new energy and battery industry, shipbuilding and marine engineering, etc.

Product Main Advantages

Precise Environmental Parameter Control: S02 corrosion test chamber employs high-precision sulfur dioxide concentration measurement and control methods, coupled with a PID intelligent temperature and humidity control system. This allows for adjustable temperature and humidity ranges, high temperature uniformity and stability, ensuring a highly consistent testing environment.
Unique Design to Prevent Condensation Dropping: The sulfur dioxide corrosion chamber top features a well-designed 120-degree apex angle, effectively preventing condensation from dripping onto the test samples and avoiding interference with test results. This detail fully demonstrates the professionalism and rigor of the equipment design.
Easy Operation and Reliable Safety: The sulfur dioxide corrosion chamber control system is located on the right side of the chamber, making operation intuitive and simple. The chamber door and body are sealed with corrosion-resistant silicone rubber, effectively preventing sulfur dioxide leakage and ensuring the accuracy of test results. The test status can be clearly observed from the outside during the test without affecting the results.
Environmentally Friendly Waste Gas Treatment System: Equipped with a special sulfur dioxide gas filtration device, it can quickly and effectively filter residual sulfur dioxide gas in the chamber after the test, ensuring that the remaining gas does not pollute the atmosphere.
Multiple safety protection mechanisms: The equipment integrates multiple protection functions such as over-temperature protection, water shortage alarm, leakage protection, short circuit protection, and overall equipment timing. In abnormal situations such as over-temperature, the equipment will automatically stop operating. It has fault protection systems for over-temperature, low water level, and overload to ensure a safe and reliable testing environment.

Sulfur dioxide corrosion chamber are specialized testing equipment that simulates the corrosive environment of sulfur-containing industrial atmospheres, playing an irreplaceable role in materials science, quality control, and reliability evaluation. Using sulfur dioxide gas as the corrosive medium, it simulates and accelerates the acid corrosion process experienced by materials in scenarios such as industrial areas, coal-fired power plants, and petrochemical plants under closed laboratory conditions by precisely controlling temperature, humidity, and gas concentration.

FAQ

Q1: How is the SO₂ concentration controlled?

It features a microprocessor PID sulfur dioxide concentration controller with timing function, combined with a precise gas dosing system and forced circulation to ensure uniform concentration distribution.

Q2: What standards does the chamber comply with?

It complies with GB/T 2423.33 (sulphur dioxide test for electrical and electronic products) and IEC 60068‑2‑42 / IEC 60068‑2‑43 (environmental testing – corrosion tests – SO₂ exposure).

Q3: Can I test complete assemblies or only flat samples?

The chamber can accommodate both individual test coupons and small assemblies. Optional custom sample racks and rotating platforms are available to ensure uniform gas exposure for complex parts.

Q4: How do I maintain the chamber and the neutralization unit?

The stainless steel interior should be cleaned after each test with a mild alkaline solution to remove acidic residues. The exhaust neutralization unit requires periodic replacement of media as per the maintenance schedule provided.
