Description
pH tester CHECK F is a compact handheld instrument for routine pH determination in the laboratory and related technical environments. It is specified for the measuring range pH 2–12 and is fitted with a glass shaft suited to direct immersion measurements in aqueous samples. The unit is supplied ready for use with batteries included, so setup is straightforward at the bench. Designed as a practical pH tester rather than a full benchtop meter, CHECK F supports quick checks of sample acidity or alkalinity during preparation, process control, or teaching laboratory work. The instrument contains lithium-ion cells and is not subject to labelling according to ADR SV188. Offered as a single piece with a net weight of 0,180 kg, it is easy to store and transport between workstations. This CHECK F model from manufacturer Dostmann fits everyday workflows where a durable glass-shaft probe and a clearly defined pH window are required without unnecessary complexity. Categories of use include general labware measuring tasks focused on pH value assessment with a dedicated pH tester format.
This article is part of pH meters, in pH & electrochemistry.

Questions about pH tester CHECK F, Glass shaft, pH 2-12., 1 unit(s)
What is this article?
pH tester CHECK F, Glass shaft, pH 2-12., 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?
