product description:
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 protection. It is a The artificial simulated gas corrosion test is to use sulfur dioxide gas to accelerate corrosion tests on materials or products under a certain temperature and relative humidity environment to test 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 lot of human, financial and material resources have been saved
.
