The sulfur dioxide test chamber is used to accelerate the corrosion test of the protective layer of metal materials, parts, electronic devices and industrial products, and quickly and easily reproduce the corrosion process of sprayed and untreated metal surfaces. The concentration of sulfur dioxide in the cabinet also has a great influence on the test results.

Next, we will introduce the control method of the concentration of sulfur dioxide in the box during the test. 1. The gas concentration is controlled by the metering cylinder buoy: observe the amount collected by the two metering cylinders in the box;
2. The gas is automatically stirred after entering the studio, and the circulation system can make the uniformity of the gas in the box more balanced;
3. The air guide tube is connected with a corrosion-resistant silicone tube, which can make the gas be smoothly introduced into the test box;
4. The exhaust fan adopts centrifugal plastic fan, which can make the exhaust gas better excluded from the box;
5. Exhaust gas is filtered by activated carbon plus soda ash and then exhausted by the exhaust fan to reduce environmental pollution.
