An electrode measuring system comprising a measuring electrode (1) and a seat (2) co-operating with the same during the measurement, the measuring electrode comprising one or more electrode surfaces (11a, 12a), and the seat comprising an inlet (16) and an outlet (17) for a fluid, a physical characteristic of which is to be measured, and a connecting duct (18) between the said inlet and outlet. The measuring system in accordance with the invention is characterized in that the measuring electrode (1) and the seat (2) are designed with two surfaces (1a, 2a) sealing against each other which between them from at least a part of the said duct (18) which runs past the said electrode surface or electrode surfaces (11a, 12a). The invention is primarily intended to be used for the measurement of the quantity of a low-molecular compound in a more complex mixture, e g glucose in blood, but can also be applied more generally. |
