Description
The pH electrode LE438-IP67 is a laboratory pH sensing electrode that carries an IP67 designation in its model identification, indicating suitability for environments where moisture protection is relevant. This electrode belongs to the pH-electrodes category and is also listed among general electrodes, conductivity sensors and oxygen sensors product groups. It has a net weight of 0,22 kg and a gross weight of 0,24 kg, making it a manageable component for routine laboratory handling and instrument connection. Supplied as one piece, the LE438-IP67 is intended for pH measurement tasks in research, quality-control and process laboratories. The electrode is manufactured by Mettler-Toledo OnLine and integrates into standard laboratory pH measurement workflows. Its construction supports everyday use with compatible meters and transmitters where a robust electrode body is preferred. The unit arrives ready for connection and calibration according to normal laboratory practice. Laboratories requiring a dedicated LE438-series pH electrode with the stated IP67 model designation can incorporate this sensor directly into existing analytical setups without additional mechanical adapters.
This article is part of pH electrodes & sensors, in pH & electrochemistry.

Questions about LE pH Electrode LE438-IP67
What is this article?
LE pH Electrode LE438-IP67 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.
