System for determining water quality with thick-film multisensor

A set of sensors for water quality measurement has been developed. It consists of a multisensor designed to measure the following parameters: pH, temperature, dissolved oxygen, conductivity, redox potential and turbidity. The system has been built-up in thick-film technology, using when possible commercially available serigraphic pastes. The multisensor can be implemented in in-situ portable or stationary instrumentation for water quality monitoring. The technology used in the multisensor implementation provides fundamental properties of miniaturisation, reasonable precision and low cost. The complete system also includes electronic acquisition, signal conditioning and computing capabilities.
