A.KRÜSS Optronic is a leading manufacturer of high precision optoelectronic measuring devices and analytical instruments. Refractometers, polarimeters, melting point meters offer intuitive user interfaces, advanced data management, intelligent user management and novel measurement documentation.

Products Include:

  • Refractometers
  • Polarimeters
  • Melting point Meters

KRÜSS polarimeters are ideal for analysing optically active substances by determining their angle of rotation. They support all applications in industry, research, development and education



A.KRÜSS 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.


With the melting point meters from A.KRÜSS, powdery substances can be examined quickly and reliably semi-automatically or fully automatically and with a precisely regulated heating rate.
