Description
The pH/Cond meter SevenDirect SD23 is a laboratory instrument designed for simultaneous pH and conductivity measurements in aqueous samples. It addresses routine electrochemical analysis needs where acidity and ionic conductivity must be recorded together, supporting buffer checks, sample characterisation and process monitoring. Supplied as one piece, the meter has a net weight of 2,8 kg and a gross weight of 4,1 kg, offering a practical bench-top format for everyday laboratory operation. The SevenDirect SD23 from manufacturer Mettler-Toledo OnLine belongs to a family of professional electrochemical meters intended for research, quality-control and educational laboratories. Combining pH and conductivity channels in a single unit simplifies workflows that previously required separate instruments, while remaining compatible with standard laboratory electrodes and accessories. Pack size is one piece, allowing straightforward integration into existing measurement stations. The instrument originates from China and is registered under WEEE number DE39797539. Laboratories that need reliable dual-parameter pH and conductivity determination will find this SevenDirect model a clear, application-focused choice for routine electrochemical work.
This article is part of Conductivity meters & cells, in pH & electrochemistry. See also pH meters.

Questions about pH/Cond meter SevenDirect SD23
What is this article?
pH/Cond meter SevenDirect SD23 is the article on this page. Luminix Health distributes Mettler-Toledo OnLine for laboratory use. It sits in Conductivity meters & cells, inside pH & electrochemistry, in Instruments de précision.
A conductivity meter and its cell measure how well a solution carries current. The cell constant is the geometry that converts conductance to conductivity, and it is calibrated with a standard. Temperature compensation matters because conductivity rises with temperature.
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.
