Description
SevenDirect™ SD20 HA kit is a benchtop pH meter supplied as a complete laboratory package for pH determination. The kit includes the InLab® Routine Pro-ISM® pH single-rod measuring cell, buffer solutions at pH 4.01, 7.00, 9.21 and 10.00 provided as 2 × 20 ml of each, an electrode holder and a protective cover. This HA configuration pairs the SevenDirect™ SD20 platform with the Routine Pro-ISM® single-rod cell for routine aqueous pH measurements. The instrument and accessories are offered from manufacturer Mettler-Toledo as one integrated unit. Packaged as 1 pc(s) with a weight of 4,590 kg, the set is prepared for immediate installation on the laboratory bench. The four buffer values support multi-point calibration across the common acidic, neutral and alkaline range. The electrode holder maintains correct sensor positioning during measurement, while the protective cover helps shield the meter between uses. Combining meter, Routine Pro-ISM® electrode, calibration buffers and handling accessories, the SD20 HA kit provides a focused benchtop solution for standard laboratory pH workflows.
This article is part of pH meters, in pH & electrochemistry.

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