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.

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