Liquid Analysis
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.
Disinfection and chlorine sensors and transmitters
Products for reliable measurement of chlorine and bromine based disinfectants
Systematic disinfection is an essential step in water treatment and legally required in many areas to protect people and systems. However, high doses of disinfectants can be toxic. Our sensors for free chlorine, chlorine dioxide, total chlorine and free bromine monitor drinking water, process and reuse water, pool water or seawater to ensure regulation-compliant disinfection.
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.
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.
