A cartridge-shaped reference element for potentiometric measuring systems exhibits a hollow body (20) as well as first and second sealed ends (30, 40) and a chamber (60). A silver electrode is provided as at least partial coating (50) of the inner surface of hollow body (20) bordering chamber (60), and coating (50) and protruding from chamber (60) so that a potential relating to the reference element can be measured.

Cartridge-shaped reference element for pontentiometric measuring systems

A reference electrode which makes use of an electrolyte which is immobilized by mixing it with an hydraulically setting inorganic material. The hydraulically setting materials that can be used are plaster of Paris, cement or mixtures thereof which can be mixed with aggregates commonly used in cements. The electrodes are characterized by ease of manufacture and stability with regard to high pressure and temperature changes.
