DEVICE FOR MEASURING THE FREE CHLORIDE CONTENT OF WATER

摘要

The invention relates to a device for measuring the free chloride content of water, said device including at least one amperometric sensor of active chloride, including a reference electrode (11), a counter-electrode (12), first (131) and second (132) working electrodes, said reference electrode (11) and first working electrode (131) being suitable for being connected to first elements for generating an electrical potential difference, said counter-electrode (12) and first working electrode (131) being suitable for being connected to current-measuring means, said counter-electrode (12) and second working electrode (132) being suitable for being connected to a means for generating an electric current, said device including a membrane (17) covering said first (131) and second (132) working electrodes, said membrane (17) contacting said working electrodes (131, 132) and including a gel suitable for allowing hypochlorous acid (HClO) and hypochlorite ions (ClO-) to pass therethrough.
