It can be used to measure moisture permeability of various coated fabrics, composite fabrics, composite membranes and other materials.

GB/T12704；ASTM E96；JISL1099；BS 7209。

1. Adjustable temperature control accuracy: 20-50 +0.1;

2. Adjustable relative humidity: 40-95%+1% RH;

3. Standard test temperature and humidity: 30 0.5 23 0.2 (water temperature);

                                                                     23 +0.5 +50%+2% RH;

                                                                     65%+2% RH at 20 +0.5.

                                                                     38 +0.5 50%+2% RH;

                                                                     38 +0.5 90%+2% RH;

                                                                     40 (+0.5 (+50%+2%) RH;

                                                                     90%+2% RH at 40 +0.5.

4. Wind speed range: 0.02-0.8m/s;

5. Wind speed regulation mode: automatic regulation and manual regulation;

6. Number of dehumidifying cup shelf layers: three layers;

7. Number of moisture permeable cups: 18 on the second floor (selected by GB, US and UK standards)+6 on the first floor by daily standard potassium acetate method;

8. The rotating speed of the moisture permeable cup holder is adjustable at 2 rpm/min and 5 rpm/min.

9. Power supply: AC220V + 10%;

10. Power: 4KW;

11. Shape size: 700 x 880 x 1760 mm;

12. Net weight: 320Kg.

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

2. The temperature and humidity sensors imported from Switzerland are used to ensure the accuracy of temperature and humidity in the experimental cabin.

3. Industrial color touch screen operation, Chinese and English menu display;

4. The instrument adopts automatic water-adding function, which is convenient for testing and suitable for long-time testing.

5. Temperature and humidity recorded once a minute can be inquired in real time and printed out by printer.

6. A three-layer sample holder with 9 test cups per layer greatly increases the number of single test samples.

It reduces the operation cost of users and improves the efficiency.

7. Sample cups are equipped with small doors to reduce the impact on the test environment after opening the door due to the sampling time.

It shortens the time of stabilization again; (It fully meets the requirements of Article 5.1.1 of GB/T12704-2009 each time.)

After closing the test compartment door, the balance must be reached again within 3 minutes.

8. The test is more uniform than that of the fixed sample holder.
