Questions about pH-mètre de poche pH 7 Vio set 2, avec électrode combinée pH GEL, 1 unité(s)
What is this article?
pH-mètre de poche pH 7 Vio set 2, avec électrode combinée pH GEL, 1 unité(s) is the article on this page. Luminix Health distributes Dostmann for laboratory use. It sits in pH electrodes & sensors, inside pH & electrochemistry, in Instruments de précision.
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.
