for testing Oxygen Transmission Rate (OTR) or Water Vapor Transmission Rates (WVTR) respectively on films from low to high barriers. They are designed for both first-time users and the advanced operator providing accurate and repeatable test results within a wide detection range.The test is complete when equilibrium, or steady state, is achieved; that is, when the sensor detects a constant amount of oxygen in the nitrogen carrier stream. The rate of oxygen permeating through the sample is not changing. This rate is the sample OTR and is recorded in units of cc/100 in 2 /24 hr or cc/m 2 /24 hr at 73°F (23°C), 0% RH.MOCON provides Water Vapor Permeation Analyzers for testing water vapor & moisture transmission rate of films and packages for many applications.
