Description
DO502 electrolyte solution for refilling DO500 electrode (30 ml) is a dedicated refill electrolyte formulated for the polarographic DO500 dissolved oxygen electrode. When the electrolyte originally supplied with the electrode has been consumed, this 30 ml bottle provides a direct replacement to restore correct sensor performance. The solution is intended specifically for polarographic dissolved-oxygen measurement and supports continued accurate DO readings after routine membrane or electrolyte maintenance. Supplied as a ready-to-use liquid in a compact bottle, it enables laboratory and process users to keep DO500 electrodes operational without interruption. This refill electrolyte from manufacturer APERA Instruments is designed solely for the DO500 electrode series. Net content is 30 ml with a corresponding net weight of 0,03 kg, making the bottle easy to store and handle beside the instrument. It is suitable for water-quality laboratories, aquaculture monitoring, environmental testing and other applications that rely on polarographic DO sensors requiring periodic electrolyte replenishment.

Questions about DO502 Electrolyte Solution for DO500 Electrode (30ml)
What is this article?
DO502 Electrolyte Solution for DO500 Electrode (30ml) is the article on this page. Luminix Health distributes APERA Instruments for laboratory use. It sits in pH electrodes & sensors, inside pH & electrochemistry, in Lab instruments.
A pH electrode is a glass membrane and a reference. It is a consumable: the glass ages, the junction clogs, and the reading drifts. A refillable electrode and a gel electrode differ in how they are maintained. The connector has to match the meter. The electrode, not the meter, is usually what is wrong.
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.
