Description
LE740 conductivity electrode is a laboratory conductivity sensor intended for measurements at low conductivities. It is fitted with a 1 m cable and a Mini-DIN connector for connection to compatible meters and readout instruments. The sensor is offered as a single-piece unit with a net weight of 0,078 kg and a gross weight of 0,162 kg, making it convenient to stock and handle in everyday laboratory setups. Designed for dilute aqueous media and other low-ionic-strength samples, the LE740 supports conductivity work where reliable readings in the lower range are required. From manufacturer Mettler-Toledo OnLine, this electrode suits analytical, quality-control, and water-testing laboratories that need a dedicated low-conductivity probe with a Mini-DIN interface. Its clear cable length and connector type simplify instrument matching, while the single-piece pack size fits routine replenishment of electrode inventories. Use the LE740 wherever low-conductivity monitoring forms part of standard laboratory workflows and sample characterisation.

Questions about Cond probe LE740
What is this article?
Cond probe LE740 is the article on this page. Luminix Health distributes Mettler-Toledo OnLine for laboratory use. It sits in Conductivity meters & cells, inside pH & electrochemistry, in Lab instruments.
A conductivity meter and its cell measure how well a solution carries current. The cell constant is the geometry that converts conductance to conductivity, and it is calibrated with a standard. Temperature compensation matters because conductivity rises with temperature.
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.
