Measurement cell for coulometric measurement of thickness of metal coating on base material has reference electrode that is at least partly annular between outer sleeve and application element or at least partly on or in application element

摘要

The measurement cell has an outer sleeve (17) with an outlet opening for an electrolyte and a connection for a pressure medium at one end, an inner sleeve (18), a first chamber (19) between the sleeves, a second chamber (21) in the inner sleeve, an inner sleeve opening (22) near the outer sleeve outlet opening (24) via which the chambers communicate and an application element (36) that bounds the measurement surface (33). A reference electrode (26) that is annular at least in one section is arranged between the outer sleeve and the application element or at least partly on or in the application element. An independent claim is also included for an application element for a measurement cell.
