Potentiometric sensor for pH determination and method for forming a connection between a shaft tube and a glass membrane of a potentiometric sensor

摘要

A potentiometric sensor (1) for pH determination comprising a shaft tube (4) and a glass membrane (3), wherein the shaft tube (4) and the glass membrane (3) form a first chamber, in which an inner electrolyte (5) of the sensor (5) 1) and a discharge element (7) of the sensor (1), wherein the sensor (1) also outside the first chamber, a reference element (8) and a reference electrolyte (6), wherein the glass membrane (3) and / or an the glass membrane (3) adjacent transition region (100) is made by a generative process, and a method for establishing a connection between the shaft tube (4) and a glass membrane (3) of a sensor (1).
