Water Vapor Permeability Tester | The Key to Accurate Fabric Air Circulation Testing

DESCRIPTION / TECHNICAL SPECIFICATIONS

Introducing a precision laboratory instrument used to determine the resistance of textiles and textile composites to water vapor penetration. This device is an essential apparatus for measuring the "breathability" property of fabrics, which is a crucial quality factor, especially for sportswear fabrics and other technical materials. The test is conducted under standard room conditions, simulating real-world use to obtain relevant and reliable data. This device is specifically designed to meet strict international testing standards, including BS7209, BS3424-34, and ISO 8096.

The mechanical design of this instrument is meticulously engineered to guarantee accurate and repeatable results. The instrument consists of 8 test cups with water reservoirs and a precision drive system. One of its key advantages is the use of a flexible axle drive system. This innovation effectively isolates and avoids vibration from the motor, which could affect the water vaporization process within the testing containers. By eliminating this potential external interference, the instrument ensures that the permeability data obtained purely reflects the intrinsic characteristics of the material being tested.

Built for efficiency and consistency, this instrument can test up to 8 samples simultaneously, increasing throughput and productivity in your laboratory. During the test, all test cups move at a constant speed of 2 rotations per minute (rpm) to ensure uniform conditions for all samples. With dimensions of 810 x 410 x 250 mm and an approximate weight of 17 kg, the device has a robust yet compact design suitable for a laboratory bench. The instrument operates on AC 230V, 50Hz/60Hz power, making it compatible with standard electrical supplies.

The primary application of this tester is for evaluating textiles and textile composites, with a special focus on functional fabrics like those used in sportswear. Its ability to measure how well water vapor (perspiration) can pass through a fabric is vital information for garment manufacturers, material developers, and quality control laboratories. By providing quantitative and dependable data, this instrument plays a critical role in ensuring the comfort, performance, and quality of the final textile product.
