Scalded sausage
HK4 NIR spectralyser


Measurement of up to 4 organic componentes

  • simultaneous online- mesaurement of up to 4 organic componentes (e.g. fat, water, protein, connective tissue protein)
  • specially developed NIR (Near InfraRed) technology with diode array and therefore the first online NIR- spectrometer.
  • modular setup of evaluation unit and halogen sensor
  • transmission or reflection halogen sensor
  • no drift of the measurement values through aging of the lamps
  • independend of color changes
  • no moving parts

Trophy 2006    Innovation award:
The NIR-online-spectrometer HK4 was awarded by CFIA in France with the highest trophy measurement instruments can get in the food industry. At present the HK4 is the only online-spectrometer, to be used in raw process environment, not only in laboratories. The HK4 is developed with the latest online NIR technology with diode array and therefore directing in NIR technology.

Depending upon operational area different sensors are available.
