CRM Water Standards

Hydranal™ Certified Reference Materials (CRMs) serve as reference points that are traceable to other internationally accepted standards, such as CRMs from metrological institutes, or SI units.

These CRMs are produced and certified under ISO Guide 34 in combination with ISO/IEC 17025. These products are supplied with a printed certificate which contains a certified value, comprehensive documentation, an uncertainty calculation, lot-specific values, an expiration date, and storage information.
