Mocon says its new Permatran-W Model 398 water vapour transmission rate test system provides a low cost alternative for testing of medium to high barrier structures. Each test cell has its own sensor, assuring greater throughput with accurate results, the company claims. The unit’s precise relative humidity testing enables two films to be tested simultaneously at two different RH conditions.
Also new is the Pac Check Model 325 hand-held oxygen and carbon dioxide analyzer, which measures controlled and/or modified atmospheres in food packages. The unit can be used in production, quality control and R&D applications to verify residual percentages of O2 and/or CO2.
