Description

Refractive index is an important parameter used in determining the quality, quantity, purity or mixing ratio of a chemical substance. It is a common measurement used by a variety of industries – chemical, food & beverage, cosmetic, flavors and fragrances, pharmaceutical, metal working, petrochemical, education/research and environmental. Krüss manufactures a wide variety of  models to suit your needs from digital to manual hand-held units.

Krüss Digital Hand-Held Refractometers

Krüss Digital hand-held refractometers are ideal for mobile use and have a large measurement range. Use them to inspect incoming goods, optimize quality assurance and reduce work processes. They are lightweight and easily fit in a lab coat pocket. There are three models to choose from:

DR301-95

DR301-95 VO

  • The most advanced digital hand-held model with many features and functions found in the standard laboratory model.
  • Large measuring range and high precision
  • Choose from refractive index scale, sugar scale, salt scale plus the ability for programming 2 User-defined scales
  • Use the 9 volt battery option for mobility or the optional power supply to convert it into a small laboratory unit
  • Easy to calibrate with water
  • Temperature compensation from 5 to 40 degrees C
  • Robust casing, light weight and easy to clean

DR201-95 and DR201-95-OE

DR201-95 VO

  • Compact digital hand-held refractometer which eliminates errors caused by misreading a manual refractometer
  • Wide measuring range on the refractive index scale (1.3330 to 1.5318 nD) and the sugar scale (0 to 95% Brix)

Krüss AR/ Abbe Refractometers

Abbe refractometers measure the refractive index based on the principle of the total reflection that occurs at the boundary between a prism and a sample. Abbe refractometers are an excellent instrument to measure the refractive index of a solid sample. Two models are available:

AR2008 Digital Abbe Refractometer

AR2008 VR

  • Digital LCD display of refractive index or Brix value together with the temperature
  • Automatic temperature compensation feature
  • Measurement range of 1.3000 to 1.7200 nD; 0 to 95% Brix
  • Designed for harsh environments
  • Thermostat connections for both illumination prism and measurement prism
  • Serial RS-232 and RS-422 interfaces

AR4 Analog Abbe Refractometer

AR4 VR

  • Read results via ocular; scale division of 0.0005 nD; 0.25% Brix
  • LED illumination for prism with long LED service life. 589 nm standard with other available wavelengths on request
  • Thermostat connections available
  • Supplied with digital thermometer
