Water Vapour Permeability Tester, also called Water Vapor Transmission Rate Tester (WVTR Tester) is to determine the water vapor permeability of various textile and garment fabrics, coating fabric, composite, sportswear, and industrial fabrics. This tester complies with ASTM E96, GB/T 12704, JIS L1099, etc.

This Vapour permeability testing machine is also suitable for conducting the Moisture Vapor Transmission Rate Test of medical protective clothing.  We are a professional Auto Water Vapour Permeability Tester supplier, please feel free to contact us for a competitive price.


Waterproof and water vapor permeability fabric means that under certain pressure, water will not be immersed in the fabric, but the sweat emitted by the human body can be transferred to the outside world in the form of water vapor through the fabric, thus preventing sweat from accumulating and condensing between the body surface and the fabric in order to maintain the comfort of the garment. It is a high-tech and unique functional fabric. For ordinary fabric, waterproofing is easy to achieve, the key is how to achieve water vapor permeability.

Auto Water Vapour Permeability Tester TF165B is the instrument used to measure the water vapor permeability of various fabrics (including moisture-permeable coated fabrics) and wadding tires, space cotton, and other garment nonwoven fabrics.

Waterproof and water vapor permeability fabrics have been developed and used in the production of military and protective clothing, and are now widely used in the manufacture of sportswear, travel bags, tents, and so on. In addition, waterproof and water vapor permeability fabrics can also be used as trauma dressing, such as cotton gauze, which can keep wound skin dry, and as surgeon’s work clothes and dustproof work clothes in the clean studio, in addition to the above-mentioned uses.

Features of Auto Water Vapour Permeability Tester TF165B

More reliable test results: high precision temperature and humidity sensors, rotating sample holder with adjustable speed, ensuring each sample are evenly affected by water vapor during the test, and the results are more reliable.

Reduce cost and improve efficiency: the use of a double-layer specimen placement rack, 9 test cups per layer, greatly increases the number of samples for a single test.

Reasonable and scientific design: The specimen holder is designed with two small doors for easy sample taking and maximum avoidance of the impact on the test environment after opening the door; automatic water filling function, suitable for long time testing.

Easy to operate: chip control, color touch screen operation, modular design, intelligent control, real-time display of test time.
