    Abstract: A device and reagents to be used in conjunction therewith for the determination of the level of sulfite or related species, including sulfur dioxide (SO 2 ), in red or white wine, musts, beer, juices, water, industrial process streams and other opaque media is described. The device provides electrodes and circuits designed for amperometric detection of the titration endpoint and for indicating by sight, sound or touch when the endpoint has been reached. The reagents allow quantitative volumetric determination of the iodometric endpoint when used with the device. The sulfite or related species levels are related directly to the volume of the quantitative reagents used.
