VOC testing climate chamber

1VOC testing climate chamberpurpose：Detect the release of substances on the surface of materials at a constant temperature:

1. Modify the volatile matter and molecular material data before;

2. Compare product performance within an effective range (e.g. different colors/patterns);

3. Testing prototypes and low volatility materials;

4. During the formal certification testing period, test the product's * performance
