Description
InLab Smart Pro-ISM is a compact laboratory sensor electrode intended for precise electrochemical measurements. Belonging to the InLab family, it supports applications in pH determination, conductivity sensing and dissolved-oxygen monitoring within research, quality-control and process laboratories. The unit is supplied as a single piece with a net weight of 0,063 kg and originates from manufacturer Mettler-Toledo OnLine. Its lightweight construction facilitates easy handling and integration into existing meter systems that accept InLab Smart Pro-ISM probes. The electrode is suitable for routine analytical work where reliable signal transmission and sensor performance are required. Designed for professional laboratory environments, it complements a range of benchtop and portable instruments used for multi-parameter water and solution analysis. The sensor’s compact form factor and standardised interface enable straightforward replacement and calibration routines in daily laboratory workflows, ensuring consistent data acquisition across pH, conductivity and oxygen measurement tasks.

Questions about pH electrode InLab Smart Pro-ISM
What is this article?
pH electrode InLab Smart Pro-ISM is the article on this page. Luminix Health distributes Mettler-Toledo OnLine for laboratory use. It sits in pH electrodes & sensors, inside pH & electrochemistry, in Lab instruments.
A pH electrode is a glass membrane and a reference. It is a consumable: the glass ages, the junction clogs, and the reading drifts. A refillable electrode and a gel electrode differ in how they are maintained. The connector has to match the meter. The electrode, not the meter, is usually what is wrong.
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.
