Process Analytics for Any Kind of Water

Knick provides consultation for companies with regard to the treatment and disposal of water and supports them through liquid analysis with process reliability. pH value, oxygen, and conductivity are key parameters for optimizing these processes.

With a wide product range of sensors, industrial transmitters, fittings, and cleaning and calibration systems, Knick provides custom solutions and services.

Water – a Valuable Resource

Treating pure water and ultra-pure water is expensive, but its quality plays a decisive role in many processes. Particularly in the low conductivity area, stringent requirements are placed on the measuring range and accuracy of the sensors.

And treating wastewater such that it complies with all regulations and is risk-free, and can be returned to the cycle or fed into the environment is just as important.

Why Knick?
For maximum accuracy in ultra-pure water or durable, low-maintenance measuring technology that is easy to operate, Knick offers simple, affordable solutions from a single source – based on the requirements of the measuring loop.

Reliable, Accurate, and Easy to Operate

The product range contains everything from portable solutions with manual measurement to fully automated measuring loops that include sensor cleaning and calibration. Every single solution consists of mature Knick technology in proven quality, coupled with know-how when selecting from the wide product range.

For reliable liquid analysis, Knick uses proven Memosens technology. Thanks to the inductive Memosens bayonet coupling, Memosens is 100% watertight and resistant to contamination, corrosion, salt bridges, overpressure, and interference potentials. Using measured values and sensor diagnosis data, the process control system can control quality and processes, and affordably manage predictive maintenance as well.
