C401H Oxygen/Water Vapor Transmission Rate Test System is based on the testing principles of coulometric oxygen sensor and infrared water vapor sensor. It is designed and manufactured in accordance with standards such as ASTM D3985, ASTM F1249, and ISO 15106-2. It provides ahigh-precision integrated testing solution for water vapor and oxygen transmission rates of high and medium barrier materials. It is widely applicable in pharmaceuticals, food, medical devices, daily chemicals, photovoltaics, electronics and other fields, accurately detecting the oxygen and water vapor transmission performances of films, packaging, sheets, and related materials.
Product Features Note 1
Combining Tests of OTR and WVTR in One
Testing Principle
The pre-treated sample is clamped between the test chambers. Oxygen or nitrogen with stable relative humidity flows on one side of the film, and high-purity nitrogen flows on the other side. Oxygen or water molecules diffuse through the film into the high-purity nitrogen on the other side and are carried to the sensor by the flowing nitrogen. By analyzing the oxygen or water vapor concentration measured by the sensor, the oxygen or water vapor transmission rate and other results are calculated.
