Description
SG98-ELK SevenGo Duo pro™ pH/Ion/RDO is an electrode kit configured for dual-channel pH/ion and optical dissolved oxygen (RDO®) work with the SevenGo Duo pro™ platform. The kit pairs InLab® Expert Pro-ISM with InLab® OptiOx, giving laboratories and field users matched sensors for pH/ion-selective measurement and optical DO in one coordinated package. This combination supports multi-parameter electrochemistry where reliable electrode pairing is essential for consistent sample evaluation, method transfer, and routine water-quality checks. Delivered as one piece with a net weight of 2,043 kg, the electrode kit is intended to equip the corresponding portable meter for simultaneous channel use rather than as a standalone display unit. The SG98-ELK set from manufacturer Mettler-Toledo OnLine fits electrochemical measuring applications spanning pH meters and oxygen meters. Using ISM-enabled InLab® Expert Pro together with InLab® OptiOx helps standardise sensor setup, simplifies channel assignment on dual-channel meters, and supports efficient workflows in QC, environmental monitoring, and process-related aqueous analysis.

Questions about SevenGo Duo pH/Ion/DO meter SG98-EL-Kit
What is this article?
SevenGo Duo pH/Ion/DO meter SG98-EL-Kit is the article on this page. Luminix Health distributes Mettler-Toledo OnLine 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.
