PERMATRAN-W 101K WVTR Analyzer
Brand: MOCONThe PERMATRAN-W® 101K is a 6-cell instrument allowing you to test up to 6 samples at the same conditions simultaneously.
The unique design allows accurate true permeation measurement through the samples that reflect real-life situations.
High Accuracy
- Unique RH control allows repeatable testing to ASTM D6701
- Measures transmission rate of water vapor or moisture vapor through the porous and breathable polymer membranes, polymer coated thin paper, and thin polymer nonwoven.
- Measure WVTR of higher-level transmitters up to 101,000 g/(m2*day)
- Precise temperature measurement and control
High Throughput
- Test breathable membranes, coated paper and more
- Unique test method is faster and more accurate than Gravimetric Methods
- Parallel testing of 6 samples at a time
The PERMATRAN-W 101K is designed to test the Water Vapor Transmission Rate (WVTR or MVTR) on breathable barriers efficiently and accurately.
Testing highly permeable materials with the traditional Gravimetric method is subject to driving force issues caused by an air gap that leads to inconsistent and erroneous test results.
The 101K WVTR analyzer utilizes a modified inverted water cup concept that eliminates the air gap problem and maintains constant 100% RH throughout the test period providing accurate and repeatable results.
Designed for high transmitter barriers this analyzer provides test results from 500 to 101,000 g/(m² x day) while conforming to the ASMT D6701 standard that is specific written for this instrumental method.
The 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 fully adjustable temperature control with flow and barometric pressure correction capabilities.
For more than 25 years, MOCON’s PERMATRAN series of instruments have been the most trusted and longest lasting on the market.
The 101K offers accurate water vapor permeation measurement for those breathable barriers not easily tested by other methods.
The PERMATRAN-W® 101K is a specially designed WVTR (or MVTR) instrument for testing breathable or high transmitter barriers.

Summary of Test Method
- A dry chamber, guard film, and a wet chamber make up a diffusion cell in which the test film is sealed. A first test is made of the water vapor transmission rate of the guard film and air gap between an evaporator assembly that generates 100 % relative humidity. A sensor produces an electrical signal, the amplitude of which is proportional to water vapor concentration. The electrical signal is routed to a computer for processing. The computer calculates the transmission rate of the air gap and guard film and stores the value for further use. The barrier is then sealed in the test cell and the apparatus started in the test mode. As before, the electrical signal representing the water vapor is sent to the computer which then calculates the transmission rate of the combination of the air gap, the guard film, and the test barrier. The computer then uses this information to calculate the water vapor transmission rate of the material being tested. The computer determines when the measured results indicate that the specimens have reached equilibrium values and the testing is considered finished.
