Water vapor permeation analyzer

Water vapor permeation analyzer

PERMATRAN-W ® 101K is a 6-unit instrument that allows you to test up to 6 samples simultaneously under the same conditions. The unique design allows for accurate and realistic penetration measurements of samples that reflect the true situation.

high precision

• Unique RH control allows for repeated ASTM D6701 testing

• Measure the transmission rate of water vapor or water vapor through porous and breathable polymer films, polymer coated thin papers, and thin polymer nonwoven fabrics.

• Measuring up to 101000 g/(m)2 *The WVTR of the advanced transmitter of Tian

• Accurate temperature measurement and control

High throughput

• Test breathable film, coated paper, etc

• The unique testing method is faster and more accurate than the weight analysis method

• Parallel testing of 6 samples at once

PERMATRAN-W 101K is designed to effectively and accurately test the water vapor transmission rate (WVTR or MVTR) on breathable barriers. The use of traditional weight analysis methods to test highly permeable materials can be affected by driving force issues caused by air gaps, resulting in inconsistent and erroneous test results. The 101K WVTR analyzer adopts an improved inverted water cup concept, eliminating air gap issues and maintaining a constant 100% RH throughout the entire testing period, providing accurate and reproducible results. This analyzer is designed specifically for high emission barriers and can provide 500 to 101000 g/(m)2 *The test results of the instrument meet the ASMT D6701 standard specifically designed for this instrument method.

This instrument has an easy-to-use operator interface and can be connected to other MOCON instruments, providing centralized control and monitoring of multiple instruments. It has adjustable temperature control and flow and pressure correction functions.

For 25 years, MOCON's PERMATRAN series instruments have been the most trusted and longest lived instruments on the market. 101K provides accurate measurement of water vapor permeability for breathable barriers that are difficult to test using other methods.

Summary of Testing Methods

The dry chamber, protective film, and wet chamber form a diffusion pool, in which the test film is sealed. Firstly, test the water vapor transmission rate of the protective film and the air gap between the evaporator components that generate 100% relative humidity. Sensors generate electrical signals whose amplitude is proportional to the concentration of water vapor. The electrical signal is routed to the computer for processing. The computer calculates the transmittance of the air gap and protective film, and stores this value for future use. Then seal the barrier in the testing unit and start the equipment in testing mode. As mentioned earlier, the electrical signal representing water vapor is sent to the computer, which then calculates the transmittance of the combination of the air gap, protective film, and test barrier. Then, the computer uses this information to calculate the water vapor transmission rate of the tested material. The computer determines when the measurement results indicate that the sample has reached equilibrium and considers the test to be completed.
