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.

HK9 Spectrometer

Using the latest microwave technology at the same time both the density and moisture can be measured without contact to the product.

HK9 Vivaldi  

Moisture and density measurement

  • state of the art microwave engineering
  • modular setup of evaluation unit and sensors
  • no moving parts
  • wear-free
  • maintenance-free
  • vibrations do not have an influence on the result of measurement
  • optional remote control from a PC or separate operating device
  • non-contact measurement
  • 10 measurement/ second



Due to the robust and modular design the microwave measuring instrument HK9 is particularly suitable for the measurements of moisture and density at bulk cargo and bale on a conveyor belt.

Calibration
The calibration of the HK9 is done with our easy to use Specter9 software.
