Product Overview

The Hamilton CRM Conductivity Standard 15 µS/cm, 250 mL (Part No. 238927) is a premium ISO 17034 Certified Reference Material (CRM) developed for the calibration, verification, and routine performance qualification of conductivity meters and conductivity sensors. Formulated with a high-stability glycerine base, this certified calibration solution provides 15 µS/cm conductivity at 25°C with ±1% certified accuracy and NIST-traceable measurements. It is ideal for pharmaceutical, biotechnology, semiconductor, environmental, and laboratory applications where reliable low-conductivity calibration is essential.
