pH Sensors and Transmitters

Products for high-quality pH measurement in all industries.

More than 30% of all quality-relevant measurements in processes are pH measurements. That's why reliable pH sensors & transmitters are extremely important for plant optimization and process safety.

We offer an extensive portfolio for all conditions, such as stable processes, fast changing media compositions, sticky media, hazardous areas or hygienic applications.

Conductivity Sensors and Transmitters

Products for high precision conductivity measurement in all industries.

In many applications conductivity is crucial for process control, product monitoring, water monitoring, or leakage detection.

We provide reliable and accurate instruments for all measurement ranges and conditions, such as ultrapure water, CIP cycles, hazardous areas or hygienic processes.

Oxygen Sensors and Transmitters

Products for high accuracy oxygen measurement in all industries.

The measurement of dissolved oxygen is essential for quality assurance and process control in numerous applications such as aeration control, fermentation or inertization.

We provide instruments for reliable and accurate oxygen analysis over all measurement ranges from oxygen traces to high oxygen concentrations and for all conditions such as hazardous areas or hygienic processes.

Turbidity Sensors and Transmitters

Products for reliable turbidity and total solids / suspended solids measurement in all industries.

Turbidity measurement is essential for quality assurance and process control in a wide variety of applications such as drinking water production, effluent monitoring and sludge concentration measurement in wastewater treatment plants, monitoring of seawater inlets in desalination projects or product loss detection in dairies.

Chlorine Sensors and Transmitters

Products for reliable measurement of chlorine, total chlorine and chlorine dioxide.

Free chlorine, chlorine dioxide or total chlorine (incl. chloramines) are usually measured to monitor and control the disinfection of drinking water, reuse water or pool water.

Our sensors are therefore applied in waterworks, cooling towers, bottle cleaning facilities, etc., where they ensure a smooth water treatment compliant to legal limits..

Process Photometers

Products for inline measurement of UV absorption and NIR / VIS absorption in all industries.

Process photometers for UV absorption, NIR and VIS provide precise and compliant inline concentration, color and turbidity measurement.

Thanks to their hygienic design, they are ideally suited for chromatography, fermentation, filtration, phase separation and crystallization.

Their high temperature and pressure stability also ensure safe application in condensate monitoring or leak detection of heat exchangers.

Analyzers for Hardness, Iron, Aluminum, Chromate & Sodium

Products for highly accurate analysis in the water, wastewater and power industries.

Suppliers of drinking water and mineral water, users of process water or managers of wastewater treatment plants need to know exactly which substances are dissolved in the water to ensure consumers' health, protect capital intensive goods, achieve safe processes and optimize environmental protection.

Our water hardness, iron, chromate, aluminum and sodium online analyzers ensure good water quality in all applications

ORP Sensors and Transmitters

Products for effective ORP measurement in all industries.

Reliable ORP sensors and transmitters provide trend information on the disinfection ability in drinking water or swimming pools, aeration control in wastewater treatment plants and the detoxification of electroplating baths or flue gas scrubbing.

We offer an extensive portfolio for standard or hygienic applications and hazardous areas.

Nutrient Analyzers and Sensors

Products for high-precision analysis of ammonium, nitrate, nitrite, phosphate and total phosphorus.

Nutrient analyzers and sensors control outlets of wastewater treatment plants to ensure regulatory compliance and minimize discharge fees.

They help optimize aeration control and precipitant dosing during biological treatment of wastewater, and monitor denitrification processes to support you in supplying safe drinking water, mineral water and process water.

TOC, COD and SAC Analyzers

Products for high-precision sum parameter analysis in municipal and industrial wastewater treatment.

TOC, COD and SAC analyzers are used to assess the organic load of surface water, municipal wastewater and industrial wastewater.

They measure total organic carbon, chemical oxygen demand and spectral absorption coefficient. Measurement in the outlet ensures compliance with regulatory requirements.

In the inlet, analyzers help avoid load peaks and help optimize process control.

Automatic Water Samplers

Products for mobile and stationary sampling of water, wastewater, stormwater and surface water.

There are many reasons for sampling water or wastewater. Often it is a legal requirement, but it helps also to protect surface water, to monitor wastewater treatment processes or to identify dischargers into a sewage system. Our automatic water samplers are the smart and proven way of sampling.

The fully automated systems take samples for industrial and municipal wastewater treatment plants, water management authorities and all industrial customers where reliable water sampling is key.

Sludge Level Sensors and Transmitters

Products for reliable sludge level measurement in sedimentation tanks.

Sludge level sensors and transmitters help you to pump sludge, not water. They continuously monitor the separation and transition zones of the clarification and settling phases, so that you can operate your process efficiently.

Typical installations are at the primary and secondary clarifier of wastewater treatment plants to measure sludge level / sludge blanket level.
