Mount the pre-conditioned specimen between the dry and wet chambers. The humidity sensor located in the dry chamber analyzes humidity changes and calculates the time for humidity to increase from the lower preset value to the higher one. The water vapor transmission rate and water vapor transmission coefficient are consequently obtained by periodically system measurement and analysis.
This instrument is applicable to the determination of water vapor transmission rate of:
Including plastic films, plastic composite films, paper-plastic composite films, coextruded films, aluminized films, aluminum foils, aluminum foil composite films and many others
Including engineering plastics, rubber, and building materials, e.g. PP, PVC, PVDC and nylon
Including paper and paper board
Including solar back-sheets
Including LCD monitor films
Including textiles and non-woven materials
Including aseptic wound protecting films and face masks
This instrument is based on the humidity sensor method, and is professionally applicable to the water vapor transmission rate test of film specimens. It is equipped with three individual test dishes, and the testing process is completely automatic and conforms to international standards.
W3/130 system adopts Labthink's exclusive patent design of three diffusion cells integrated in one instrument for individual or multiple tests, which not only can test individually but also improve test efficiency by 3 times. It also utilizes the embedded computer control system that provides a better performance than traditional single chip system.
The instrument is equipped with Labthink's latest operating software, with user-friendly operating interface and intelligent data management functions. It also supports LystemTM Lab Data Sharing System, which ensures uniform management of test results and test reports.
