CRM (Certified Reference Material)
- Verification of the refractive index for refractometers
- Factory certified reference materials
- Valid for large temperature and wavelength ranges
- Refractive index samples with high precision
Certified Reference Materials (CRM)
Reference materials (also refractive index standard) from Schmidt+Haensch with high precisions over the whole temperature and wavelength range. The reference liquids are traceable to PTB standards and make a high-quality verification, calibrating or testing of your refractometer possible. You can find more at “Specifications” and you are welcome to contact us for more CRMs.
