摘要

A measurement cell with coloured indicator and its method of manufacture. The cell, intended to be immersed in a medium, includes a permeable or semi-permeable membrane (1) sheathing a thin elongate element (2), a volume of coloured indicator solution (6) contained in the elongate element (2), the variations of whose colour are indicative of the variations of the medium, and at least one opening (3) on one wall of the elongate element, for obtaining a large exchange area with the volume of coloured indicator solution and the medium, through the membrane.
