Description
Conductivity standard solution 147 µS/cm (25 °C) is a ready-to-use calibration standard for electrochemical conductivity measurement in the laboratory. The stated value is defined at 25 °C and supports routine verification and calibration of conductivity meters and related electrodes used in quality control, process monitoring, and analytical workflows. Tolerance is held to ±1 % of the stated value, giving a clear performance window for instrument checks. Traceable SRM certificates according to NIST underpin the reference character of the solution and help laboratories document calibration chains. Supplied as a 500 ml pack from manufacturer Labbox under the LABKEM product line, the standard is intended for use after opening within twelve months (six months applies to the separate COSS-10U-500 grade). Net weight is 0,580 kg. Typical applications include setup and intermediate checks of conductivity measuring systems alongside pH and dissolved-oxygen instrumentation in electrochemical laboratories.
This article is part of Conductivity meters & cells, in pH & electrochemistry. See also pH meters.

Questions about Conductivity solution 147 µS/cm (25 ºC), 500 ml
What is this article?
Conductivity solution 147 µS/cm (25 ºC), 500 ml is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Conductivity meters & cells, inside pH & electrochemistry, in Instruments de précision.
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.
