Questions about Testeur de pH CHECK G, corps en verre, pH 0-14, 1 unité
What is this article?
Testeur de pH CHECK G, corps en verre, pH 0-14, 1 unité is the article on this page. Luminix Health distributes Dostmann for laboratory use. It sits in pH meters, inside pH & electrochemistry, in Instruments de laboratoire.
A pH meter reads the electrode and displays pH, after calibration with at least two buffers. A meter that cannot be calibrated is a voltmeter. Resolution to 0.001 is not the same as accuracy. Portable and benchtop meters differ in the electrodes they accept and in the data they store.
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.
Which category should I open next?
The category is pH & electrochemistry. The sub-category is pH meters. The catalogue is Instruments de laboratoire.
