ABSTRACT:
The invention relates to measuring the concentration of ions in a medium. The potentiometric sensor of the invention comprises a body (7) in the form of a matrix body made of a single type of material which does not conduct electricity, which is chemically inert, and which is suitable for being filled with various materials in the dispersed, the dissolved, or the grafted state. A sensitive zone of the matrix body comprises a layer or thickness (9) of an ionically conductive material for being put into contact with the measurement solution, an underlayer or thickness (10) of an electronically conductive material, and an intermediate layer or thickness (11) providing intimate connection between said layer (9) and said underlayer (10). A conductor (12) passes through a portion of the matrix body (7) in sealed manner and is inserted into the underlayer (10). The sensor is particularly applicable to measuring biological fluids.
