Abstract

En fargeindikator-målecelle beregnet på å bli dyppet ned i et medium, omfatter en permeabel eller semipermeabel membran () som dekker et tynt, lang-strakt organ (2), et volum med en fargeindikator-opplosning (6) som befinner seg i det langstrakte organ 2 og hvis fargevariasjoner indikerer variasjo-ner i mediet, samt minst en åpning 3 på en vegg av det langstrakte organ for å oppnå en stor utveks-lingsoverflate mellom volumet med fargeindikator-opplosning og mediet gjennom membranen.A color indicator measuring cell intended to be immersed in a medium comprises a permeable or semipermeable membrane () covering a thin, elongate member (2), a volume of a color indicator solution (6) contained therein. elongate member 2 and whose color variations indicate variations in the medium, and at least one opening 3 on a wall of the elongate member to achieve a large exchange surface between the volume of color indicator solution and the medium through the membrane.
