Refractometer

Certified Reference Materials (CRM)

  • Verification of the refractive index for refractometers
  • Factory certified reference materials
  • Valid for large temperature and wavelength ranges
  • Refractive index samples with high accuracy
Certified Reference Materials (CRM)

Reference materials (also refractive index standard) from Schmidt+Haensch with high accuracies 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.
