Abstract

The invention relates to a device for measuring concentrations of liquid media, simultaneously using several physical measuring methods. Said device is especially in a miniature form, comprising a sensor system (1) and a long measuring body (2) which consists of a body base (3); a long reflecting body (4) which is positioned on said body base, which has a square cross-section, and in which a polarised measuring beam is irradiated which enables a refractometric and an ATR-spectrometric measurement to be taken simultaneously; also comprising two measuring chambers (5a, 5b) which are arranged on two reflecting sides lying opposite each other on the reflecting body, said measuring chambers extending over the whole measuring body in the longitudinal direction and being externally defined by bi-directional permeable membranes (6a, 6b). More than two measuring chambers (5) can be provided. The outer ends of the measuring chambers can be covered by a reflecting optical element (7) or reflecting layers (13). The measuring chambers (5) and the body base (3) can contain further measuring devices.
