Moisture measurement

  • state of the art microwave engineering ISM- Band
  • Particularly designed for the measurement of thin layers from 0,1 cm to 1,0 cm, depending of water content
  • wear-free
  • maintenance-free
  • optional remote control from a PC or separate operating device


The HK5 is particularly designed for the measurement of water or moisture in very thin layers. Since many years many good results are archived in the measurement of paper, cardboard and chip boards. The sensors can be installed either directly on the paper machine or on the conveyor belt.
Depending on the measured area there are up to 4 pairs of sensors used. It is able for moisture measurement in thin layers from 0,1 cm to 1,0 cm.
