Beschrijving
CellOx® 325-3 is a galvanic oxygen sensor equipped with the OxiCal®-SL calibration and storage vessel for practical dissolved oxygen measurement workflows. It features a waterproof plug rated IP 67 and an extended cable length of 3 m, allowing greater reach during laboratory or on-site sampling. The delivery package includes grinding foil, three exchange membrane heads and electrolyte solution, enabling immediate preparation of the sensor. Cleaning solution RL-G 205204 is not part of the set and should be ordered separately. Offered by manufacturer WTW - a Xylem brand, the CellOx® 325-3 supports oxygen determination in water analysis, environmental monitoring and process applications where a longer cable is advantageous. The OxiCal®-SL vessel simplifies calibration steps and safeguards the membrane during storage and transport. Net weight is 0,5175 kg and gross weight 0,575 kg. With its complete accessory kit and durable connector, this galvanic sensor provides a ready-to-use solution for routine dissolved oxygen work requiring a 3 m cable.

Questions about CellOx® 325-3, Galvanic oxygen sensor with OxiCal®-SL calibration and storage ve
What is this article?
CellOx® 325-3, Galvanic oxygen sensor with OxiCal®-SL calibration and storage ve 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 Instrumenten.
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.
