Description
Benchtop pH meters SevenDirect™ SD20 Standard kit supply the core meter hardware for laboratory pH measurement without a preselected sensing electrode. The package includes an electrode holder and a protective cover so the instrument can be installed neatly on the bench and shielded when not in use. A pH single-rod measuring cell is not included and must be ordered separately, allowing laboratories to choose the electrode that matches their samples and methods. Provided as 1 pc from manufacturer Mettler-Toledo, the SevenDirect™ SD20 Standard kit is suited to users who already standardise on specific InLab® or other compatible sensors, or who need flexibility across different applications. Quality-control, teaching and research environments can build a modular pH workstation around this base unit. The protective cover helps keep the display and housing clean in busy lab surroundings, while the holder supports stable electrode positioning during measurement and storage. Unit weight is 4,130 kg per the product data. This standard configuration is the starting point for SevenDirect™ SD20 benchtop pH setups when the measuring cell is specified independently.
This article is part of pH meters, in pH & electrochemistry.

Questions about Benchtop pH meters, SevenDirect(TM) SD20 Standard kit, 1 unit(s)
What is this article?
Benchtop pH meters, SevenDirect(TM) SD20 Standard kit, 1 unit(s) is the article on this page. Luminix Health distributes Mettler-Toledo 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?
