title: A method for reducing the flow-sensitivity of a polarographic dissolved-oxygen sensor.
abstract: A method for reducing the flow-sensitivity of polarographic dissolved-oxygen sensors has been modelled mathematically and tested experimentally. The improved probe uses a two-layer membrane: the first layer is made of Teflon and the second of silicone rubber, which is more permeable than Teflon to oxygen. This arrangement reduces the flow-sensitivity to about 4% of that for a single-membrane 1-mil Teflon; second membrane 2.5-mil silicone rubber. (b) First membrane 0.5-mil Teflon; second membrane 5-mil silicone rubber.
