HK1 - M


Concentration- and moisture measurement

  • sate of the art microwave engineering
  • modular setup of evaluation unit and sensors
  • no moving parts
  • no wear
  • vibrations do not have an influence on the result of measurement
  • maintenance-free
  • optional remote control from a PC or separate operating device
  • up to 16 different calibrations
  • temperature sensor PT100 is standard, optional NTC possible

Due to the robust and modular design the microwave measuring instrument HK 1-M is particularly suitable for the measurements of concentration and water content in the food- , primary and chemical industry.

Depending upon operational area following antennas are used: We advise you gladly which antennas for which application or measuring kind the best results supply.
