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
Applications

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

Digitales Handrefraktometer DR101-60

DR101-60

As an entry-level model for the digital refractometry, the DR101-60 covers the measurement ranges between nD 1.3330–1.4419 and 0–60 % Brix. Thanks to the automatic temperature compensation for the Brix scale, you can achieve reproducible measurement results even under changing environmental conditions. As a water-tight device, the DR101-60 meets IP65 code and can be cleaned under running water.

Digitales Handrefraktometer DR201-95

DR201-95

The compact handheld refractometer DR201-95 oŽers an extended measurement range of the refractive index and the sugar content of nD 1.3330–1.5318 and 0–95 % Brix. The automatic temperature compensation for the Brix scale helps the user with the measurements of beverages and sugary confectionary products. The device is splash-proof and meets IP64 code.

Digitales Handrefraktometer DR301-95

DR301-95

As a mobile handheld device or digital tabletop unit, the DR301-95 can measure the refractive index or the sugar content within a measurement range of nD 1.3330–1.5318 or 0–95 %Brix. In addition, the device measures the salt content and allows for the use of two additional freely definable scales. The automatic temperature compensation for the Brix scale can be optionally connected. A USB interface allows you to send measured data to a PC or a printer at any time. An alarm option can be set up for monitoring the limit values in production processes. The provided mains adaptor turns the DR301-95 into a small lab refractometer; for a mobile use it is operated with a 9 V monobloc battery.
