Refractometer

Refractometers measure refractive index of liquids, pastes and solids

Refractometers measure the refractive index of liquids, pastes and solids with high precision. In close cooperation with well-known partners from industry and research, we have developed refractometers that can be easily integrated into existing processes in the laboratory.
