Coulometric Sensor Method C200 Series Oxygen Transmission Rate Test System . Oxygen Transmission Rate (OTR) Test System is designed and manufactured based on the coulometric sensor method (aka. equal pressure method) and conforms to ASTM D3985 and ISO 15105-2.Those two methods have their respective advantages: differential pressure method has no requirements for testing gas, and can be used to test the transmission rate of any gas. Thus, this method can be used to test nitrogen transmission rate without further costs.CO2 transmission rate test by weighing method: Water vapor transmission rate test by inverted cup method: Non-destructive test for packaging seal performance: Multi-station packaging pressure test: Tensile test of packaging materials with ultra-long elongation: Heat-seal strength test for cap films of medical bottles, yogurt cups and jelly cupsThe Differential Pressure Method is also referred to as Manometric Method. During the test, as shown on the graph below, one side of film on that side of chamber is exposed to a flow of test gas (e.g.: O2, CO2), the other side of the chamber is usually vacuumed. . In this case, OTR testing should be set with precise RH so that their worst .
