Abstract
The invention relates to a sensor with two electrodes and a non-conducting iaphragm arranged between them. The electrodes have an insulating coating, which preferably comprises a metal oxide, mixed metal oxide, metal nitride, inorganic insulating material or fluorocarbon and the non-conducting diaphragm a metal oxide, mixed metal oxide, inorganic or organic insulating materials. As a function of the intended use, the diaphragm and electrode coating are porous (for measurements in non-aqueous liquids) or non-porous (for measurements of aqueous liquids). It is also directed at a process for measuring the characteristics of a liquid with the sensor according to the invention, as well as to the use of the sensor for the continuous or discontinuous investigation of liquids.
