Description
Conductivity standard 147 µS/cm 250 mL is a ready-to-use calibration solution for conductivity meters and related sensors in laboratory and process analytics. The standard is traceable to certified international SRM-NIST reference materials, supporting documented calibration chains for quality systems and routine instrument verification. Supplied in a 250 mL pack, it is suited to multi-point or single-point checks around the low-to-mid microsiemens range commonly used in pure-water monitoring, buffer preparation control, and general aqueous conductivity work. Net content weight is 0,25 kg with a gross weight of 0,301 kg. Offered by manufacturer Mettler-Toledo OnLine, this conductivity standard helps laboratories maintain measurement consistency across meters, probes, and online cells that require regular verification against a defined 147 µS/cm value. Use according to your instrument manufacturer’s calibration procedure, allowing temperature equilibration and clean electrode handling to preserve accuracy. The solution supports analytical, industrial, and quality-control workflows where NIST-traceable conductivity references are specified. Pack size is one piece, convenient for bench stock or scheduled recalibration cycles without excess volume.

Questions about Cond. Std. 147 µS/cm 250mL
What is this article?
Cond. Std. 147 µS/cm 250mL 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.
