Abstract

A method and an apparatus tests liquids. When the method is implemented, following a reaction of constituents in the liquid with the maximum quantity at least of one free oxidizing agent and/or reagent contained in the liquid, the quantity of oxidizing agent and/or reagent remaining in the liquid is displayed visually as a measure of the quantity of constituents in the liquid reacting with the oxidizing agent and/or reagent. For implementing the method, use is made of a sensor that is configured as a sheet-like structural element and is provided with at least one inlet opening, a sample-accommodating channel, a mechanical pump, a transporting capillary, a detection zone, an emptying channel, and an outlet opening.
