Auto Water Vapour Permeability Tester - TNG1052

The TNG1052 is designed to determine the water vapor transmission rate of materials. It operates by measuring the amount of water vapor that passes through a sample under controlled conditions. The instrument supports testing according to ASTM E96, GB/T 12704, and JIS L1099. It uses high-precision temperature and humidity sensors to ensure accurate results. The test environment is maintained within a temperature range of 18 to 50°C and a humidity range of 40% to 95%. The TNG1052 features a rotating sample holder with adjustable speed to ensure even exposure of samples to water vapor. It includes a double-layer rack with 9 test cups per layer, increasing the number of samples that can be tested simultaneously. The machine also has automatic water filling for long-term testing and a color touchscreen interface for operation. The modular design and intelligent control system allow for real-time monitoring of test duration. The TNG1052 is suitable for a wide range of materials, including waterproof and moisture-permeable fabrics used in military, protective clothing, sportswear, travel bags, tents, and medical applications such as trauma dressings.

The water vapor permeability test results are more reliable. The test uses high-precision temperature and humidity sensors. It also uses a rotating sample holder with adjustable speed. This ensures that water vapor evenly affects each sample during the WVTR test.

It reduces cost and improves efficiency. It uses a double-layer rack with 9 test cups per layer. This setup boosts water vapor permeability test samples by a large margin.

The holder of this WVTR Tester is designed with two small doors for sample putting. This avoids impacting the test environment after opening the door. The WVTR tester also has automatic water filling for long-term testing.

It is easy to operate. The WVTR tester has chip control and color touchscreen operation. It also has a modular design and intelligent control. It displays water vapor permeability test time in real-time. All of these features contribute to a perfect performance water vapor permeability tester.

Waterproof and Moisture-permeable fabrics are more and more popular. It keeps the sweat from building up and condensing between the body and the fabric. It keeps the garment comfortable. It is a high-tech and unique functional fabric. Waterproofing is easy for normal fabric. The key is to improve water vapor permeability. The water vapor transmission rate testing is becoming increasingly important in textiles.

The is an Auto Water Vapour Permeability Tester. It measures the water vapor permeability of fabrics. It works on many fabrics. These include coated ones that let moisture through, as well as wadding tires, space cotton, and other nonwoven garment fabrics.

The fabrics are waterproof and let water vapor through. They are used to make military and protective clothing. Now, they are widely used to make sportswear, travel bags, tents, etc. Waterproof, vapor-permeable fabrics can also be used as trauma dressings. They are like cotton gauze. They keep wounds dry. They are also used as surgeons and dustproof work clothes in the clean studio.

• ASTM E96: Standard Test Methods for Water Vapor Transmission of Materials
• GB/T 12704: Textiles-Test method for water-vapor transmission of fabrics-Part 1: Desiccant method
• Test Principle of Water Vapor Transmission Rate Testing.
• In a constant temperature and humidity test room, we place the permeable cup. We put the specimen in the cup and sealed it with a rubber gasket. We then place the permeable cup with water and fabric in the sealed room. The room has the specified temperature and humidity. We calculate the permeable amount by measuring the change in the cup’s quality. The cup includes the specimen and moisture absorbent or water. This change occurs within a certain period.
• Strictly meet standards
• All data for the WVTR testing machine meet the standard parameters.
• Consistency with international third-party laboratories
• The water vapor permeability test data are comparable to the WVTR test results obtained by well-known international third-party laboratories.
• High repeatability
• With the same set of samples and the same WVTR tester, after multiple tests, the results of water vapor transmission rate testing will remain consistent.
• High reproducibility
• The same set of samples, and different machines of the same model, after multiple WVTR tests, the results will remain consistent.

What is the Water Vapour Permeability of Fabric? Water vapor permeability definition: In general, there is a water vapor pressure difference between the front and the back of the fabric, so the water vapor diffuses from the high-pressure air side to the low-pressure airside through the fabric. The water vapor permeability of fabric refers to the difficulty degree of water vapor passing through the fabric. The water vapor permeability of fabric is an important index to measure the comfort of clothing. Due to the difference of clothing environment, it is necessary to choose the appropriate water vapor permeability test method. The Principle of Water Permeability Test A test specimen is sealed over the open mouth of a test dish that contains water, and the assembly is placed in a controlled environment.
