Abstract

In order to have a reaction chamber 101 which is independent of the indicator chamber, in an optode 100 comprising an indicator and a membrane enclosing the indicator, for measuring concentrations of material particles 103 by means of an optical light measuring device comprising a light source, a light receiver and a display, a reaction chamber 101 containing at least one reagent, sealed off by a membrane 1010 and intended for the material particles 103 to be measured is connected in front of the optode 100. <IMAGE>
