Description
DO503 membrane caps are a set of replacement membrane caps for the polarographic DO500 electrode. The pack contains three DO503 membrane caps intended as spare parts for the DO500 dissolved-oxygen sensor. These exchangeable caps allow straightforward renewal of the sensing membrane on the DO500 electrode used with compatible meters of the SX700 series. Regular replacement of the membrane cap supports continued polarographic measurement of dissolved oxygen in aqueous solutions. Supplied as a convenient three-piece set, the product ensures that laboratory and field users keep ready spares on hand. Compatibility is specified exclusively for the DO500 electrode. The DO503 membrane caps form an essential consumable accessory within the dissolved-oxygen measurement range offered by manufacturer APERA Instruments. Each set provides three individual DO503 membrane caps ready for installation whenever membrane renewal becomes necessary, helping maintain electrode readiness and measurement continuity without extended downtime.
This article is part of pH electrodes & sensors, in pH & electrochemistry.

Questions about DO503 membrane caps (3 pcs, for DO500 electrode)
What is this article?
DO503 membrane caps (3 pcs, for DO500 electrode) 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.
