Process analytics for any industrial water

Knick advises companies on the treatment and disposal of water and supports them with process-safe liquid analysis. pH, oxygen and conductivity are important parameters for the optimization of these processes.

A broad portfolio of sensors, process analyzers, holders and fittings, cleaning and calibration systems allows Knick to offer tailor-made solutions and services.

Water - a precious resource

Treating pure and ultra-pure water is costly, but its quality is crucial for many processes. Particularly in the conductivity range, which is so low, great demands are placed on the measuring range and the accuracy of the sensors.

It is equally important to treat the wastewater so that it can be reused in the cycle or discharged into the environment in compliance with all regulations and without risk.

Pure and Ultra-pure Water

Process Water

Boiler Feed Water


Why Knick ?
Whether highest accuracy in ultrapure water or durable, low-maintenance and easy-to-use measurement technology: Knick is able to provide simple and cost-effective solutions completely according to all requirements of the measuring point from one source.

Reliable, accurate and easy to use

The range extends from portable solutions with manual measurement to fully automated measuring points that also include cleaning and calibration of the sensors. Each individual solution consists of the sophisticated Knick technology in proven quality, paired with expertise in selecting from the broad portfolio.

For reliable liquid analysis, Knick relies on the proven Memosens technology, which thanks to the inductive Memosens bayonet coupling is absolutely waterproof and resistant to dirt, corrosion, salt bridges, overpressure and interference potentials. With the measured values and sensor diagnostic data, the process control systems can control quality and processes as well as cost-effectively manage predictive maintenance.
