The Acid (CASS) Test Chamber is designed to test the corrosion resistance of product surfaces made of various materials after electroplating, anodizing, spraying, anti-rust oil and other anti-corrosion treatments.
RT-723 Acid (CASS) Test Chamber The artificial simulation of a salt spray environment test is a testing equipment with a specific volume space, the salt spray test chamber, which uses manual methods to create a salt spray environment in its volume space to assess the quality of the product’s salt spray corrosion resistance performance. Compared with the natural environment, the chloride salt concentration in its salt spray environment can be several or tens of times higher than the salt spray content in general natural environments, greatly increasing the corrosion rate. The time required to obtain salt spray testing results on products is also greatly shortened. Suppose a product sample is tested under natural exposure conditions. In that case, it may take up to 1 year for it to corrode, while testing under artificial simulated salt spray conditions only takes 24 hours to obtain similar results.

Box Structure
1. The overall molding is welded at high temperatures, corrosion-resistant, easy to clean, and leak-free.
2. The tower spray system is equipped with a salt liquid filtration system, without a crystallization nozzle, the salt spray is evenly distributed, and the sedimentation is freely adjusted.
3. The box cover is made of transparent material to clearly see the test items and spray in the box.
4. A water-sealed structure is used between the box cover and the box body to prevent salt spray from overflowing.
5. The circuit control board and other components are fixed in a position that is easy to inspect and maintain. The door lock opening edge cover door is used, which is not only beautiful but also convenient for maintenance.
The neutral salt spray test is currently the most widely used accelerated corrosion testing method in various fields. It uses 5% sodium chloride saline solution, and the solution PH value is adjusted in the neutral range (6-7) as the solution for spray. The average experimental temperature is set at 35 ℃, and the settling rate of salt spray is required to be between 1-2ml/2000px. h.
