Versaperm - Coulometric Oxygen Sensors
Coulometric oxygen sensor systems employ two chambers with a specimen mounted as a sealed semi-barrier between them. One chamber contains oxygen while the other is slowly purged with a stream of a carrier gas such as nitrogen
As the oxygen gas permeates through the specimen into the carrier gas, it is transported to the coulometric detector where it creates an electric current with a magnitude that is proportional to the number of oxygen atoms flowing into the detector.
This method can produce extremely accurate results.
At Versaperm we are not tied to any specific sensor types or manufacturer and so we can always select exactly the right sensor for an application. Versaperm is a world technology leader in the measurement of gas permeability. We offer not only instruments but also comprehensive testing and consultancy services.
