Liquid analysis

Environmental protection, consistent product quality, process optimization and safety – just a few reasons why liquid analysis is becoming increasingly essential. Liquids such as water, beverages, dairy products, chemicals and pharmaceuticals have to be analyzed day in and day out. We support you in fulfilling all these measuring tasks with application know-how and cutting-edge technologies. Discover our comprehensive portfolio and choose the product best suited to your process needs.

pH sensors and transmitters

pH measurement is the most important quality-relevant parameter in industrial processes. Check out our extensive offering of ISFET, enamel or glass pH sensors, transmitters, assemblies and pH buffers. Learn more.

Conductivity sensors and transmitters

Conductivity measurement is crucial for process control, product and water monitoring, or leakage detection. Check out our wide range of conductive and toroidal conductivity sensors and transmitters. Learn more

Oxygen sensors and transmitters

Discover our oxygen sensors and transmitters for quality assurance and process control in water, wastewater, chemicals, power plants, life sciences, pharma, food & beverage and fish farming. Learn more.

Chlorine sensors and transmitters

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. Learn how our chlorine, chlorine dioxide and total chlorine sensors and transmitters can support also your application by clicking on the following link.

Automatic water samplers

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. Discover our automatic water samplers for monitoring and sampling wastewater, sewer systems, surface waters, rivers, stormwater and more!

ORP sensors and transmitters

ORP measurement is an effective, low-cost method to determine the oxidizing or reducing properties of a medium. Check out our extensive offering of ORP sensors, transmitters, assemblies and buffers! Learn more.

Process photometers

Process photometers enable accurate and reproducible concentration measurement by determining UV absorption, NIR & VIS. Check out our broad offering for life sciences, food, chemical and oil & gas. Learn more.

TOC, COD and SAC analyzers

Browse through our wide range of TOC, COD & SAC analyzers for municipal and industrial wastewater. They measure total organic carbon, chemical oxygen demand and spectral absorption coefficient. Learn more.

Sludge level sensors and transmitters

Our sludge level sensors and transmitters help you to pump sludge, not water. Check out our portfolio for all sedimentation tanks in wastewater treatment plants, water treatment plants and utilities. Learn more.

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.
