Abstract

The disclosure includes an apparatus for determining a measured value in a liquid medium, comprising at least a light transmitter, at least one light receiver assigned to the transmitter, a measuring chamber that can be filled with the medium, wherein an optical path runs through the measuring chamber from the transmitter to the receiver. The apparatus includes a dosing apparatus for dosing at least one reagent and/or the medium, and for inserting the dosed reagent and/or the medium into the measuring chamber. The dosing apparatus is designed as a tube, and the tube includes at least a first control point, wherein the volume in the tube from a starting point to a first control point defines the amount of reagent or medium to be inserted into the measuring chamber. The disclosure further includes the use of the apparatus and a method for dosing the reagent.
