ABSTRACT:
An electrochemical sensor having multiple measuring zones (34) that are sequentially insulatable, disposed on the circumference of an insulating disc (1) and associated with each other by peripheral current collectors (16, 17) which extend radially inward up to central zones where they form contacts (23, 24) for a measuring apparatus. The disc-sensor also has a device (6) for rotating the disc, and guide marks for positioning (11) and for isolating (7) the measuring zones (34), and may be contained in a housing (40). The invention is useful in the quantitative analysis of glucose.
