A single rod measuring probe has a hollow probe portion which contains an electrolyte solution and an electrical connector plug. The hollow probe portion and electrical connector plug are joined by a refill unit which receives the probe portion and plug in opposite ends thereof. The refill unit includes a lateral opening for filling the probe portion with electrolyte solution and a slidable cover for closing the opening. The slidable cover includes an elastic seal which seals the lateral opening when the cover is over the lateral opening. Preferably, the refill unit is non-circular in cross-section to facilitate venting.

Single-rod measuring element for electrochemical measurements

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.
