Harrer & Kassen HK1 - M

Concentration- and water content- measurement

newest digital microwave engineering
modular setup of evaluation unit and sensors
no moving parts
no wear
no maintenance necessarily
vibrations do not have an influence on the result of measurement
alternative remote maintenance from a PC or separate operating device

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 sensors and antennas are used:

Pin antennas for the inline measurement in tubes or a tank/vessel
Horn antennas for measurement on a conveyor belt
Spiral antennas for measurement on a conveyer belt
3A-spiral antennas (with 3A-flow cell) for the measurement in tubes (food industry)
Short 3A pin antennas (with flow cell) for the measurement in tubes
Mini-spiral antennas (with flow cell) for the measurement in tubes

We advise you gladly which antenna for which application or measuring kind the best results supply.
