1. A measuring transducer, which is embodied to produce and output a measurement signal dependent on the content of H+ and/or OH−
- ions present in a measured medium, comprising;
at least one polymer membrane selectively conducting H+ and/or OH−
ions, in a region provided for contact with the measured medium, wherein;
conduction of H+ and/or OH−
ions occurs intrinsically by means of structural diffusion by transfer of H+ ions and/or OH−
ions between neighboring functional groups of said polymer membrane;
said polymer membrane comprises an OH−
ion conducting polymer.

Abstract
A measuring transducer, which is embodied to produce and output a measurement signal dependent on the content of H+ and/or OH− ions present in a measured medium, wherein the measuring transducer has, in a region provided for contact with the measured medium, at least one polymer membrane selectively conducting H+ and/or OH− ions. The polymer membrane can comprise an H+ ion conducting polymer and/or an OH− ion conducting polymer.
