We have been developing, producing and selling high-quality products and services, with a focus on interface technology and process analytic for 75 years. As a family-owned and run company with nearly 200 employees, the city of Berlin has been the center of our economic activities since our inception in 1945.

Our innovations are based on an intensive exchange of knowledge and expertise between us and our suppliers, customers and sales partners. Our “Knick transducer”, for example, has been a synonym for high-precision transmitters for decades, and in modern liquid analysis, Memosens technology has been established as process standard.

Industrial transmitters for pH, ORP, conductivity and oxygen. 2- or 4-wire configuration, explosion-protected.

Bus communication: HART, FOUNDATION Fieldbus, Profibus DP and PA. Robust industrial housing with high IP protection. Suitable for outdoor applications. For analog and digital sensors. Easy and intuitive operation. From the DIN rail transmitter to the fully modular system.

Automatic Cleaning and Calibration Systems

Fully automatic process monitoring in combination with the Protos process analysis system and a SensoGate or Ceramat retractable fitting. Highly accurate measurements even with difficult process conditions such as high pressure, high temperatures and high levels of impurities.

Maximum availability of the point of measurement: Calibrating without disrupting the process, even when measuring directly in the pressure vessel.

Industrial Sensors

pH, ORP, conductivity and oxygen sensors for industrial applications. Analog and digital Memosens….

For measuring pH, ORP, conductivity or oxygen in industrial applications, we offer analog as well as digital Memosens-sensors.

They enable low-maintenance and highly precise measurements in the chemical, pharmaceutical and food industries, as well as in the areas of energy and the environment.


Holders and fittings from Knick provide safety and convenience when it comes to measuring pH, ORP, dissolved oxygen and conductivity. The product range extends from immersion, inline and flow-through fittings over retractable fittings up to fully automatic calibration and cleaning systems.

Our process fittings are suited for use in tough environments, e.g. at high pressures, high temperatures and in highly corrosive or aggressive media.

Our retractable fittings are the first choice for applications in chemicals, pharmaceuticals, paints, oil and sugar. Also included in our portfolio: Knick retractable fitting for fiber optic sensors. Whether PVDF, PEEK or stainless steel – thanks to flexible in-house manufacturing our fittings are available in a variety of materials suitable for every process adaptation.
