  • The models of the ORF-S series are precise, universal, maintenance-free digital hand refractometers.
  • They are characterised by their easy handling and robustness
  • Their handy design makes them suitable for convenient and quick everyday use
  • The ORF-S series is protected against dust and splash water according to the international protection class IP65. You can rinse the refractometer under running water after use.
  • The large and clearly readable TFT colour display with integrated temperature display supports the user in the reliable determination of the measured value.
  • The large selection of models with simple or multiple measuring scales enables use in many areas of application.
  • The optimised instrument software can output measured values in different measuring scales
  • The integrated automatic temperature compensation (ATC) enables simple and fast operation, as no manual conversion of the measurement result is necessary.
  • The factory calibration of the refractometer ensures immediate use and exact measurement of your sample

Application range salt
The following models are particularly suitable for measuring the content of NaCl (salt) in water. This is often used in the production and cooking of sauces, brines for pastries, the production of sheets (e.g. brine cheese), marinades for meat and the preparation of seafood. Optionally, the refractive index can also be displayed. Optionally, the refractive index can also be displayed.
