Description
InLab 731-2m conductivity electrode with 2 m cable and mini-DIN connector is a conductivity sensor intended for medium to high conductivity measurements. The design combines a very robust epoxy shaft with a 4-pole graphite cell and a cell constant of 0,57 cm⁻¹. Measuring range is given as 0,01–1000 µS/cm, covering typical laboratory conductivity applications. Shaft length is 120 mm and shaft diameter is 12 mm for standard immersion in sample vessels. Electrical connection uses a fixed cable terminated with a mini-DIN plug, and the electrode is ideal for SevenMulti devices. This InLab 731-2m conductivity electrode from manufacturer Mettler-Toledo OnLine is offered as 1 pc and has a net weight of 0,209 kg. Compared with shorter-cable variants, the 2 m cable provides extra reach between instrument and sample without changing the sensor head geometry. The epoxy shaft and graphite four-pole cell support durable everyday use. Integrate the electrode into quality-control, process-support or general analytical conductivity work where a mini-DIN interface and extended cable length are required.

Questions about Cond probe InLab 731-2m
What is this article?
Cond probe InLab 731-2m 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.
