Beschreibung
Conductivity sensor InLab 731 Pro-DES is a four-pole graphite conductivity electrode that incorporates an integrated temperature sensor for automatic temperature compensation. It is engineered for general laboratory applications covering samples of normal to high conductivity, delivering stable cell-constant performance across a wide measuring range. The robust graphite poles resist fouling and provide durable contact surfaces suitable for aqueous solutions encountered in routine quality control and research. Digital DES connectivity supplies automatic sensor recognition and diagnostic information to the connected meter, simplifying setup and verification. Net weight is 0,099 kg, keeping the probe light and convenient for handheld or stand-mounted use. Supplied as a single piece from manufacturer Mettler-Toledo OnLine, the electrode supports reliable conductivity determination in process samples, buffer solutions and other media where four-pole geometry minimises polarisation effects. Laboratories benefit from the combination of integrated temperature measurement and digital data transfer, ensuring consistent results without separate temperature probes or manual compensation steps.

Questions about Cond Sensor InLab 731 Pro-DES
What is this article?
Cond Sensor InLab 731 Pro-DES 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 Präzisionsinstrumente.
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.
