New sensor system for drinking water quality

A sensor system suitable for measuring qualitative changes In the chemical and the bacterial content in drinking water is presented. The sensor, an electronic tongue, is based on a voltammetric technique and is therefore robust, simple and sensitive to small changes of water quality in the measured sample. The sensor system is constructed so the liquid sample will flow through the sensing unit while measuring continuously. The sensor has a solid construction, does not contain any fragile parts and is independent of how it is positioned. This creates new approaches and the sensor can easily be mounted on a underwater vehicle for continuous inspection of drinking water reservoirs and continuously monitor the quality of the water as well as be mounted directly on a drinking water tap.
