Profile: Biosensores, S.L. focuses on the research in biosensor technology for its application in automated chemical and microbiological analysis. We have developed products for the analysis of parameters of water quality automatically, on-line. Our multiparameter system is an automated monitoring system that measures up to 7 classical parameters of water quality such as pH, conductivity, dissolved oxygen, and turbidity. Its analytical process is executed by the microprocessor. Biocounter is an automated device for on-line monitoring of the concentration of total micro-organisms in water samples. POLYTOX-RES is used for automated real-time monitoring of the overall toxicity presented in water.
