Description
DurOx® 325-3 galvanic oxygen sensor with OxiCal®-D calibration and storage vessel is a ready-to-use dissolved-oxygen measuring electrode for laboratory and field applications. The sensor is supplied complete with a waterproof IP 67 connector, a 3 m cable, one exchangeable membrane head, electrolyte and abrasive foil, allowing immediate commissioning after installation. The integrated OxiCal®-D vessel supports convenient calibration and safe storage of the sensor between measurements, helping maintain readiness and measurement consistency. Designed for reliable oxygen determination, the galvanic measuring principle and robust construction make the DurOx® 325-3 suitable for routine water analysis, environmental monitoring and process control tasks. Note that the cleaning solution RL-G must be ordered separately. This complete sensor set from manufacturer WTW - a Xylem brand is delivered as a single unit and provides a practical, self-contained solution for laboratories and field teams that require a durable galvanic oxygen electrode with straightforward calibration and storage capability.

Questions about DurOx® 325-3, Galvanic oxygen sensor with OxiCal®-D calibration and storage vess
What is this article?
DurOx® 325-3, Galvanic oxygen sensor with OxiCal®-D calibration and storage vess is the article on this page. Luminix Health distributes WTW - a Xylem brand for laboratory use. It sits in Dissolved oxygen & multiparameter meters, inside pH & electrochemistry, in Lab instruments.
A dissolved-oxygen meter reads oxygen in a liquid, optically or with a Clark cell. A multiparameter meter adds pH, conductivity or both on one instrument. The sensor cap or the membrane is the consumable. A reading in air and a reading in water are different calibrations.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
