Description
pH tester CHECK G is a compact handheld pH measuring instrument with a glass shaft for direct determination of pH in aqueous samples. It covers the full measuring range pH 0–14, supporting acid, neutral and alkaline solutions encountered in laboratory, educational and field-check environments. The glass-shaft design is suited to general aqueous media where a classic glass electrode geometry is preferred. The tester is supplied as 1 pc, includes batteries and weighs 0,186 kg, so it is ready for immediate portable use. According to the manufacturer Dostmann, the unit contains lithium-ion cells and is not subject to labelling according to ADR SV188. Typical applications include quick pH checks of buffers, process water, rinse solutions, teaching experiments and routine sample screening before more detailed laboratory analysis. CHECK G provides a straightforward tool for spot measurements where a full benchtop pH meter is unnecessary, combining a wide pH window with a glass shaft in a lightweight handheld format.
This article is part of pH meters, in pH & electrochemistry.

Questions about pH tester CHECK G, Glass shaft, pH 0-14., 1 unit(s)
What is this article?
pH tester CHECK G, Glass shaft, pH 0-14., 1 unit(s) is the article on this page. Luminix Health distributes Dostmann for laboratory use. It sits in pH meters, inside pH & electrochemistry, in Lab instruments.
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?
