Product Description:

Qualtech Products Industry Water Vapor Permeability Tester is a precision Automatic Water vapor Permeability Analyzer to evaluate the Permeability of Porous Samples at the touch of a button.

This professional Water Vapor Permeability Analyzer is a fully automatic Water Vapor Permeability Tester and is engineered to measure the Vapor Transmission of Barrier Materials with Low Moisture Barrier Properties, Medium Moisture Barrier Properties and High Moisture Barrier Properties offering a wide testing range combined with an excellent testing efficiency. The high-precision Sample Area integrates a high-precision Balance and analyses porous samples with high accuracy and high precision and performs a detailed sample test analysis with the included advanced PC Software. Temperature and Humidity and Water Vapor are measured with highest accuracy and sample test reports are automatically generated in PDF format.

Instantly and automatically measure the Water Vapor Transmission Rate WVTR of a wide range of samples including, Plastic Films, Foils, Aluminum Foils, Membranes, Ceramics, Sheet Materials, Rubber, Medical Pads, Pharmaceutical Membranes, Pharmaceutical Fabrics and many more. 

The Water Vapor Permeability is the ability of Water Vapor to permeate and penetrate Solid Porous Samples. The Water Vapor is usually called Permeate.  The Water Vapor Permeability is a physical property which is determined by the combination of Permeability of the sample, the Mass Diffusivity of the sample and the Concentration Gradient of the Water Vapor.

The Water Vapor Permeability Test Method is a Gravimetric Test to analyze the Transmission Rate of Water Vapor through Solid Porous Samples. A precision engineered reservoir is filled with a desiccant or with distilled water. Under specified controlled temperature and humidity conditions the weight of the water reservoir is continuously measured to analyze the Water Vapor Permeability of samples.
