电导率水 CRM (0 mS/cm)

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.
