Product features:

1. Large screen color touch screen, Chinese and English menu operation interface;

2. The standard testing environment module and moisture permeability testing module are designed in a separate way, and the internal wind speed of the box will not affect the moisture permeability testing module, and the temperature and humidity are more uniform;

3. The standard test environment module can be used separately as a constant temperature and humidity chamber;

4. The standard test environment module meets the standard requirements, and the specified temperature and humidity are reached again within 3 minutes after closing the box door;

5. The moisture permeability testing module is equipped with a dedicated air duct and a variable frequency control method to make wind speed, temperature, and humidity more stable;

6. The moisture permeability testing module is equipped with high-precision wind speed sensors to monitor the wind speed of the test air duct;

7. The equipment can be tested by either placing desiccants in a test cup for external humidity control for weight gain, or by testing the water in the cup for external humidity control for weight loss experiments

8. Intermittent weighing equipment that meets standard requirements, equipped with an automatic intermittent weighing testing mechanism, and the weight sensor can automatically reset during the testing process

9. 2-layer cup holder design, standard with national standard moisture permeable cups;

10. Rotating sample holder for more uniform sample testing results;

11. Refrigeration system: The original imported French "Taikang" refrigeration unit ensures long-term stable operation of the entire machine;

12. Utility model patented product, patent number: ZL 2020 2 2347247.4;
