Abbe refractometer KRÜSS AR4
  • -5%
KRÜSS Abbe refractometer KRÜSS AR4

The KRÜSS AR4 is a classic Abbe refractometer. The scales can be set manually using the drive knob and the refractive index and Brix values are read off using an eyepiece. The temperature is measured with the integrated digital thermometer and displayed on the LCD. The AR4 refractometer can be connected to a circulation thermostat for temperature control. This device can be used in a wide range of applications: for identity checking, purity control and concentration determination of raw materials, semi-finished products and end products or for determining the sugar concentration as well as for incoming and outgoing goods inspection.

Digital Abbe refractometer KRÜSS AR2008
  • -5%
KRÜSS Digital Abbe refractometer KRÜSS AR2008

KRÜSS AR2008 is an Abbe refractometer in which the sample is placed between a measuring and illumination prism. The device can measure the refractive index or Brix value and display the measured value together with the temperature on the LCD display. Using the serial interface, the measured values, date and time can be transferred directly to a PC or printed. These devices can be used in a wide range of applications: e.g. in the chemical, petrochemical, oil and grease industries, the food industry, in the pharmaceutical environment and in research & education.

  • Measurement of liquid and viscous samples, regardless of their viscosity
  • Measurement of films possible and of solid samples that have at least one smooth side
  • Wide measurement range from nD 1.3000-1.7200 and 0-95 %Brix
  • Digital representation of the measurement data
  • Integrated thermometer
  • Hose connections for temperature control with a circulation thermostat
  • Automatic temperature compensation for the BRIX scale can be switched on as an option
