DR101-60, DR201-95 and DR301-95

Digital handheld refractometers DR101-60, DR201-95 and DR301-95

Digital on-site measurements at the touch of a button

The mobile measurement with a digital handheld refractometer saves time as random checks or the regulation of mixing ratios can be carried out directly on the site. The measurement results are determined at the touch of a button and shown on the display. Unlike in the case of the analogue handheld refractometers, the digital determination
of reproducible measurement results does not depend on the user’s interpretation

  • Automatic measurement
  • High measuring accuracy
  • Fast to fill and clean
  • Sample tray made of stainless steel
  • Robust housing and low weight
  • Automatic temperature compensation (Brix scale)
  • Display of the measurement results in different units
  • Very simple operation

Typical applications

The digital hand-held refractometers DR101-60, DR201-95 and DR301-95 are the ideal solution for the chemical, petrochemical, automotive, aviation, metal processing and food industry as well as for hospitals and pharmacies.

  • Characterisation tests in research and development
  • Identity test, purity control and concentration determination of raw materials, semi-finished products and end products
  • Tracking of chemical processes during production
  • Outgoing goods inspection
  • Stability test
  • Determination of the sugar concentration
  • Incoming and outgoing goods inspection
  • Checking medicines for pharmacopeias
  • Analysis of body secretions
