Description
SevenDirect™ SD20 LowVol kit is a benchtop pH meter configured as a complete laboratory measurement package for pH determination in low-volume samples. The kit comprises the InLab® Micro Pro-ISM® electrode together with buffer solutions at pH 4.01, 7.00, 9.21 and 10.00, supplied as 2 × 20 ml of each value, plus an electrode holder and a protective cover. This ready-to-use assembly supports routine calibration and measurement workflows where sample volume is limited. The SevenDirect™ SD20 platform and matching accessories are offered from manufacturer Mettler-Toledo as a single coordinated unit. Packaged as 1 pc with a total weight of 4,600 kg, the LowVol kit arrives prepared for bench installation. The included buffers cover the commonly used calibration points across acidic, neutral and alkaline ranges, while the electrode holder positions the Micro Pro-ISM® sensor securely during operation. The protective cover helps shield the instrument when not in use. Together these components form a focused benchtop solution for laboratories requiring reliable pH readings on small sample aliquots.
This article is part of pH meters, in pH & electrochemistry.

Questions about Benchtop pH meters, SevenDirect(TM) SD20 LowVol kit, 1 unit(s)
What is this article?
Benchtop pH meters, SevenDirect(TM) SD20 LowVol 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.
