说明

一般描述

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.
