WATER MONITOR project will provide a monitoring system of water sources, both quantitative and qualitative, on the basis of a new analysis technology set up. This innovative instrumentation, an UV-Vis spectrometer, enables the tests of water quality in real time, providing a complete monitoring of water characteristics measuring in stable way the concentration of important substances present in the liquid such as nitrates, organic carbon and detergents. Through the combination and optimisation of data acquired from optics sensor and electronics sensor, the spectroscope make effective the analysis of the collected champions and translate instantaneously the data collected in an optical spectra. The instrument can be connected with the main transmission and processing devices therefore transmitting in real time the processed spectra.
