HK4 NIR spectralyser

HK4  

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.

HK8

HK8  

NIR-H2O-Meter
Unique LED- online moisture measurement

  • state of the art NIR-LED technology
  • no mechanically moved parts
  • specially designed for measuring of bulk material
  • the measured surface can be smooth, planar or bulk material
  • Colour has no influence on the measured signal
  • no maintanance
  • easy to use calibration software


The HK8 is a device for continuous NIR reflection measurement with infrared LED's. The NIR-H2O-Meter is a modular unit, evaluation and sensor system are mounted in different housings. The distance between sensor system and product can be up to 50 meters.

The measured value of the H2O content is available as digital (RS232, optional RS485) and analogue value (0/4-20mA).

Advantages:
In contrast to conventional IR or NIR systems from other suppliers, the HK8 does not work with color filters or halogen lamps, and offered therefore improved stability of the measurement. The lifetime is up to 10 years. The drift of the measurement value, as is the case with other IR / NIR instruments, has been fully compensated. Colourvariations of the product has no influence in the measuring result. Also uneven surfaces of the product, such as coarse bulk materials, can be measured. The HK8 has a very high reliability and very low maintenance costs.

Measurement Design:
The sensor system is located over the detected product surface. The products (e.g. paper webs, width of material and any kind of bulk material) are moving on a conveyor belt under the sensor system.
