Description
Replacement electrode for pH tester SD 50 is a spare sensing electrode intended for the SD 50 handheld pH tester. It restores measurement capability when the original probe is worn, damaged or no longer within acceptable response, supporting continued pH checks in laboratory and field settings. The electrode is supplied as a single unit and is matched specifically to the SD 50 instrument platform. Offered by manufacturer Tintometer, this replacement part keeps existing testers in service without requiring a full instrument exchange. With a low weight of 0,015 kg it is easy to store and handle as a maintenance spare. Typical use includes routine pH monitoring of aqueous samples in quality control, education and general laboratory workflows where the SD 50 tester is already deployed. Keeping a compatible replacement electrode on hand reduces downtime and helps maintain consistent pH measurement readiness. The item belongs to the pH testers and measuring-instruments category and is packed as one piece for straightforward stock replenishment.
This article is part of pH electrodes & sensors, in pH & electrochemistry.

Questions about Replacement electrode f. pH tester SD 50, 1 unit(s)
What is this article?
Replacement electrode f. pH tester SD 50, 1 unit(s) is the article on this page. Luminix Health distributes Tintometer 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.
