Application

Potassium chloride solution is a certified reference material intended for use in aqueous solution as a calibration standard for the measurement of the conductivity cell constant or as a control sample.

General description

This certified reference material (CRM) is directly traceable to the corresponding primary reference material from the Physikalisch Technische Bundesanstalt (PTB), Germany. The electrolytic conductivity of this standard is determined using a conductivity meter from an accredited Merck calibration laboratory.

Please visit ISO certificates and Site Quality Self-Assessments to access the current certificates of accreditation.

Download your certificate at https://www.sigmaaldrich.com/US/en/documents-search to view certified values, including uncertainty and expiry date.
