Handheld Refractometers

Mobile in use and proven a thousand times over

The handheld refractometers are easy to use, very robust and require no batteries. The devices differ mainly in the selectable scales, e.g. for the determination of the salt content, water content in honey, serum protein content, Oechsle, Brix and potential alcohol content as well as ethylene- and propylene glycol content. No manual conversion is required thanks to the scales and application errors are ruled out.

  • Small size for mobile use
  • Automatic temperature compensation
  • High resolution of the scale areas
  • Robust and compact design
  • Easy calibration and adjustment

 

Typical applications

The handheld refractometers HR series are the ideal solution for the petrochemical, automotive, aviation, metal processing and food industries.

  • Identity test and concentration determination
  • Outgoing goods inspection
  • Stability test
  • Quality and purity control of raw materials and end products
  • Determination of the sugar concentration
  • Determination of water content in honey
  • Examination of urine samples
