Cm Remarks

To ask this CRM send an e-mail to mrc-solicitacao@inmetro.gov.br,The CRM consists of a solution prepared gravimetrically from the dissolution of potassium chloride in deionized water (with initial electrolytic conductivity less than 0.1 μS/cm). Before bottling, the prepared solution was stirred for 48 hours. The CRM was bottled into a 3.3 borosilicate glass bottle containing approximately 250 mL of solution.

Intended use

Cm Use

The CRM has its use for the calibration of electrolytic conductivity meters, quality control of
electrolytic conductivity measurements and characterization of new batches of CRM electrolytic
conductivity. The commutativity of this material was not evaluated.
