Coulometer WTD is a device for routine moisture analysis developed by the Diram company. Water determination method employs the titration approach of Karl Fischer with coulometric generation of the titrant (iodine).
The set consists of the electronic equipment itself and a glass titration vessel into which the analyzed sample is introduced. One filling of the vessel is enough for making number of analyses up to the total amount of water cca 0.2 g and the solution usability is limited by its dilution. The vessel can work with or without a diaphragm, separating generating and auxiliary electrodes.
