QUALITY CONTROL SYSTEM FOR WVTR TESTING PERMATRAN-W® Model 398 Water Vapor Transmission Rate Test System WVTR/MVTR The new, easy to use, PERMATRAN-W Model 398 is the latest water vapor transmission rate system in a long line of quality systems available from MOCON, the world leader in permeation technology. This simple, low maintenance system conforms to the new ASTM Standard E-398 and produces the accurate and reliable data the industry has come to expect only from MOCON. The low-cost Model 398 is designed for medium to high barriers and allows for two ﬁlms to be tested independently. Each test cell has its own sensor, assuring greater throughput with accurate results. Because the Model 398 provides for precise relative humidity testing, two ﬁlms may be tested simultaneously at two different RH conditions! The new WinPerm™, Windows® based software, is simple and intuitive. Automated temperature and relative humidity control, as well as automatically determined equilibrium, all but eliminate operator error. Software has the following features: • Real time sensor analysis • Stored calibration history • Test method storage and retrieval • Quick start feature • Built-in help menu Conforms to ASTM Standard E-398 • Two, 50 cm2 independently operated test cells, each containing state-of-the-art sensor technology • For testing medium to high barriers • Broad range of automatic temperature and RH testing • Modular systems allow for control of up to ten modules from a single computer • Compatible with PERM-NET™ database and networking software • Set of three calibration ﬁlms provided • CE, UL, CSA Listed • Ideal for polymer
