This equipment is used to test the protective layers of electrical and electronic products, electroplating products and various metal products. It is used to assess the ability of materials and their protective layers to resist corrosive gases and to compare the process quality of similar protective layers. It is an artificial simulated gas. The corrosion test is to use sulfur dioxide gas to conduct accelerated corrosion tests on materials or products under a certain temperature and relative humidity environment, and compare the degree of damage suffered by the product's protective layer within a certain time range. It can also be used to evaluate the ability of certain products to resist corrosion by corrosive gases. The test results show that a large amount of human, financial and material resources have been saved.
my country has adopted the sulfur dioxide gas corrosion test as a national standard and has made detailed regulations.
Reference standards
This test equipment is produced in strict accordance with the national standards promulgated by my country/Sulfur dioxide corrosion test of metal and other non-organic coatings under normal condensation, German standard Sulfur dioxide corrosion test in saturated environment and international standards. Other standards currently in use regarding corrosion of sulfur dioxide and hydrogen sulfide gases.

Equipment structure
The control part of this corrosion test equipment has a beautiful appearance design on the right side, a reasonable structure, and smooth, natural and smooth lines.
The box material is made of high-quality plastic plates, the appearance is smooth and bright, corrosion-resistant, easy to clean and leak-free, and various auxiliary equipment
The accessories and facilities are also made of corrosion-resistant materials.
The box cover material is a high-quality transparent plate, which can clearly observe the conditions of most specimens in the room without affecting the test results.
To open the lid, you only need to gently lift the lid. The angle of the lid is designed to be the optimal top angle so that the mist generated during the test will not drip onto the sample and affect the test results.
The box cover and box body are water-sealed to prevent gas from escaping, which may affect the test results, corrode other equipment in the room, and even cause harm to test operators.
The sample rack is designed according to national standards. The upper and lower layers are specially made of corrosion-resistant materials and are tilted in degrees and degrees.
The box heating is a tank-type heating method that saves water and electricity resources. It heats up quickly and distributes temperature and humidity evenly.
There is a sulfur dioxide gas inlet pipe at the bottom of the box. The concentration of sulfur dioxide gas at the bottom of the box is controlled by a qualified flow meter. The generated sulfur dioxide gas waste treatment device is located on the back wall of the box. The whole set of equipment is equipped with a sulfur dioxide gas cylinder. A bottle of pressure reducing valve and a paraffin barrel.
The bottom of the test chamber is equipped with a gas pressure relief hole to prevent equipment damage caused by excessive pressure in the chamber.
The bottom of the equipment is equipped with movable casters to facilitate moving the equipment.
