Description
DO electrode LE621-IP67 is an electrode for dissolved oxygen measurement designed for laboratory oxygen determination. The LE621-IP67 model carries an IP67 rating in its designation, indicating suitability for environments where ingress protection is required. Offered as one piece with both net and gross weight of 0,119 kg, the electrode presents a compact form factor for integration into dissolved-oxygen measuring systems. This sensor is available from manufacturer Mettler-Toledo OnLine and originates from the United Kingdom. It is grouped among electrodes, conductivity sensors, oxygen sensors and pH electrodes, reflecting its role in multi-parameter laboratory instrumentation. The pack configuration of 1 pc addresses single-unit replacement or initial equipping. With a consistent mass of 0,119 kg, handling remains straightforward during installation or calibration routines. Laboratories performing dissolved-oxygen analysis can employ the LE621-IP67 according to the model identity and protection class provided. No further performance grades or certifications are stated beyond the electrode type, IP67 marking and recorded physical data.

Questions about LE DO Electrode LE621-IP67
What is this article?
LE DO Electrode LE621-IP67 is the article on this page. Luminix Health distributes Mettler-Toledo OnLine for laboratory use. It sits in Dissolved oxygen & multiparameter meters, inside pH & electrochemistry, in Lab instruments.
A dissolved-oxygen meter reads oxygen in a liquid, optically or with a Clark cell. A multiparameter meter adds pH, conductivity or both on one instrument. The sensor cap or the membrane is the consumable. A reading in air and a reading in water are different calibrations.
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.
