ABSTRACT:
The invention relates to an analyzer for liquids with at least one module (10) including a measuring line (14) having a reference electrode (16) and at least one measuring electrode (18). Measuring pads (48) borne by a carrier (80) can be pressed onto the measuring line; when out of contact therewith, they can be moved to and fro. The carrier may be elongated and adapted for sliding along a guiding rod (76). A spring-biased bar parallel thereto is pivotable and guides the carrier (80) as the latter is moved, e.g. when engaged by a tappet (68) of a motor-driven crank disk (66). A module chamber (30) is flow-connected to the measuring line (14) via a capillary aperture (28) in a flexible supply tube (26). Expediently, the capillary aperture (28) limits the leakage of an electrolyte in the chamber (30) to a maximum rate of 0.1 .mu.l per 24 hours at ambient pressure and ambient temperature.
