【Scope of Application】

Used for testing the moisture permeability of various materials such as coated fabrics, composite fabrics, and composite films.

【Instrument Features】

1．The refrigeration system adopts a French Taikang refrigeration unit to ensure the long-term stable operation of the entire machine.

2．It uses a Swiss-imported temperature and humidity sensor to ensure the accuracy of temperature and humidity in the test chamber.

3．It adopts industrial color touch screen operation with Chinese and English menu display.

4．The instrument is equipped with an automatic water filling function, which facilitates testing and meets the needs of long-term testing.

5．The temperature and humidity recorded once per minute can be queried in real time, and can be connected to a printer for printing output.

6．It uses a two-layer sample holder, with 9 test cups per layer, which greatly increases the number of samples in a single test, reduces the user's operating costs, and improves efficiency.

7．Each sample cup has a small door for access, which reduces the impact on the test environment caused by opening the door when taking samples, and shortens the re-stabilization time. (It fully complies with the provisions of GB/T12704～2009 Clause 5.1.1, which requires that after each closing of the test chamber door, the balance must be re-achieved within 3 minutes.)

8．The turntable-type sample holder ensures more uniform testing compared with the fixed-type sample holder.
