Sensor holder part for change fittings for glass electrodes for pH value or redox measurement has pressure medium connection sleeve for pushing into casing with inner supporting surface for variable fixing of reservoir according to length

摘要

The sensor holder part has a cylindrical casing (7) with a bottom tube connector (3) and a reversibly attached pressure medium connection sleeve on the opposite side. It has a fixed supporting surface for the electrolyte reservoir (23) formed at the transition from the cylindrical casing to the tube connector. The pressure medium connection sleeve is a sensor-fixing sleeve (9) that can be pushed into the casing with an inner supporting surface (17) for variable fixing of the reservoir according to its length.
