Liquid Analysis

Liquid Analysis

Liquid analysis encompasses the instrumentation used to measure chemical and electrochemical parameters directly in process and utility streams, as well as supporting lab and sampling workflows. The Endress+Hauser portfolio includes pH and ORP, conductivity, turbidity, disinfection/chlorine, oxygen, TOC/COD/SAC analyzers, nutrient analyzers, analyzers for hardness/iron and other constituents, process photometers, microwave transmission measurement, laboratory instruments, and automatic water samplers—covering both sensing and complete measurement stations. 

These measurements are increasingly essential for environmental protection, consistent product quality, process optimization, and safety. Daily analysis of media such as water, beverages, dairy products, chemicals, and pharmaceuticals enables tighter control of reactions, separations, cleaning, and compliance-related monitoring. A broad portfolio matters because analytical problems vary widely: some require robust in-line sensing, others require reagent-based analyzers, and still others depend on representative sampling and documentation.

Value is created when the measurement chain is engineered for accuracy and maintainability, not just initial installation. Digital sensor approaches (e.g., converting the measured value to a digital signal and transferring it without a contacting connection) support consistent signal quality and can simplify handling of calibration and sensor replacement. Mechanical integration—flow assemblies, retractable housings, and hygienic designs—reduces contamination risk and enables safer servicing for challenging or regulated processes.

Typical applications include disinfection and nutrient monitoring in drinking water and wastewater, pH control in neutralization, conductivity and oxygen monitoring in utilities, and turbidity/solids tracking in clarification and filtration. In food and beverage and life sciences, analytical measurements support CIP verification, fermentation monitoring, product release criteria, and water-system oversight. In chemicals, they enable tighter endpoint detection, improved yield, and early warning of contamination or off-spec trends across continuous and batch operations.

Liquid analysis is also a data problem: results must be traceable, integrated, and actionable. Modern communication interfaces and protocols support seamless integration into control strategies and plant asset management, while standardized platforms reduce spare parts variety and speed commissioning. Endress+Hauser positions its offering from standard sensors through complete measuring stations across key parameters, coupled with application know-how and life-cycle support.
