Since 1945 we are developer and manufacturer of sensors in Germany. In our sensor production in Meerbusch we produce pH, ORP, conductivity, and disinfectant sensors.


Our sensors are useable in all different types of application: ultra pure water sensors, specially designed process sensors, and dirt and poison -resistant sensors for industrial waste water.

Highly sophisticated

For our sensors we rely on premium materials and best processing. Our metal electrodes e.g. consist of gold or platinum with a purity of 99,99%.
