【Scope of application】
It is used for moisture permeability testing of various coated fabrics, composite fabrics, composite films and other materials.
【Relevant Standards】
GB/T12704；ASTM E96；JISL1099；BS 7209；
【Scope of application】:
It is used for moisture permeability testing of various coated fabrics, composite fabrics, composite films and other materials.
[Meet the standard]:
GB/T12704；ASTM E96；JISL1099；BS 7209；
[Instrument features]:
1. The refrigeration system adopts French Taikang refrigeration unit to ensure the stable operation of the whole machine for a long time;
2. Adopt temperature and humidity sensors imported from Switzerland to ensure the accuracy of temperature and humidity in the experimental chamber.
3. Industrial color touch screen operation, Chinese and English menu display;
4. The instrument adopts the automatic water addition function, which is convenient for testing and suitable for long-term testing needs;
5. The temperature and humidity recorded once a minute can be queried in real time, and can be connected to the printer to print out;
6. Adopt three-layer specimen placement rack, 9 test cups per layer, which greatly increases the number of samples in a single test, reduces the user’s operating cost and improves efficiency;
7. The specimen cup is equipped with a small door to reduce the impact on the test environment after opening the door due to the time of sample collection, and shorten the re-stabilization time; (After closing the test door every time in full compliance with Article 5.1.1 of GB/T12704~2009, the balance must be reached again within 3 minutes)
8. The turntable specimen placement rack is more uniform than the fixed specimen rack.
