Description
InLab® OptiOx optical sensor is an optical probe for dissolved oxygen measurement that combines RDO® technology with ISM® intelligent sensor management. Built for laboratory dissolved-oxygen work, it provides an optical sensing approach suited to aqueous samples in research, process support and quality-control settings. The sensor is supplied as one piece, with a net weight of 0,16 kg and a gross weight of 0,32 kg, making it practical for routine bench use and instrument pairing. RDO® optical detection and the registered ISM® interface support modern meter connectivity and sensor handling without reliance on classical electrochemical cells. Offered by manufacturer Mettler-Toledo OnLine, the InLab® OptiOx optical sensor integrates into standard laboratory workflows where reliable dissolved-oxygen data are required. Its compact form and defined mass facilitate installation, transport and storage within typical lab material inventories. Laboratories specifying optical DO sensors with ISM® capability can use this unit as a dedicated measurement element for dissolved oxygen. The product belongs to the laboratory materials category and is intended for professional scientific use with compatible readout systems.

Questions about DO sensor InLab OptiOx
What is this article?
DO sensor InLab OptiOx 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.
