RI-04K - Refractive Index Certified Reference Material at 15 °C, 20 °C, 25 °C and 30 °C

ISO/IEC 17025 and ISO 17034 Refractive Index Certified Reference Materials (CRM) and Standards intended to be used for verification of measuring equipment, method validation, method verification, or other quality control processes used to determine refractive index.

Each Refractive Index CRM provides traceability of measurement to recognised national standards, and to units of measurement realised at the National Physics Laboratory (NPL) or other recognised National Metrology Institutes (NMIs). All refractive index values are traceable and each CRM provides low levels of uncertainty, ensuring maximum accuracy of data at hand.
All materials are supplied with certified data for refractive index at 15 °C, 20 °C, 25 °C and 30 °C with full traceability and uncertainties are stated on the certificate provided.

ARO’s Refractive Index Standards are packaged in tamper-evident glass bottles ensures the CRM maintains contaminant-free and of high quality. ARO also offers kits for each refractive index CRM, providing easy and efficient procurement solutions for end-users.
