PERMATRAN-W® Model 398 Water Vapor Transmission Rate Test System
The new and improved, user-friendly, PERMATRAN-W Model 398 is the latest water vapor transmission rate system from a range 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.
This low-cost model has been designed for both medium and high barriers which allow the user to test two ﬁlms individually. Each test cell is equipped with its own sensor, assuring greater throughput with results that are accurate. Because the Model 398 produces 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 stability, all but eliminate operator error.
