Endress+Hauser Unveils Three Liquid Analysis Products at 2026 Suzhou Water Launch Event

Endress+Hauser Unveils Three Liquid Analysis Products at 2026 Suzhou Water Launch Event

In July 2026, Endress+Hauser held its 2026 Liquid Analysis New Product Launch in Suzhou under the theme "Gather for Innovation." Industry experts, partners, and business representatives from across the country exchanged views on water industry trends and liquid analysis innovation and applications, and witnessed the release of three new products. Facing green low-carbon, digital operations, and smart manufacturing trends, water quality monitoring is shifting from basic measurement toward more reliable, efficient, and intelligent process management. Customers increasingly value maintenance, system integration, and full-lifecycle value as much as the measurement result itself.

Three new products covering key water treatment scenarios

• CA75 DPD free/total chlorine analyzer
• CAS41E nitrate and ammonia sensor
• CUS71E next-generation sludge interface meter

The three products target drinking water, wastewater, and industrial water treatment. They are optimized around measurement performance, maintenance convenience, digital capability, and total cost of ownership. A delivery and project-signing ceremony was also held, opening a new phase for application and market promotion.

From source to supply: making water quality monitoring continuous and reliable

In tap water, residual chlorine is a key indicator. Endress+Hauser's new online monitoring solution covers water quality scenarios from source to supply, helping users track process status in time and optimize operations with reliable data.

CA75 DPD Free/Total Chlorine Analyzer — features:

• Detects free or total chlorine; suits drinking water, wastewater, industrial source water, and cooling water chlorination, handling complex conditions without alkaline pH interference.
• Factory-built calibration curve; works with the Liquiline platform for fast system connection.
• Adjustable analysis cycle, minimum 2.5 minutes; one reagent set runs the instrument at least 30 days at a 2.5-minute cycle.
• Reagent lasts 3 months after activation at room temperature (2 years unactivated).
• Flow sensor for real-time sample flow monitoring; standard 4–20 mA output plus Modbus RS485, PROFIBUS DP, and more.

For wastewater: supporting fine operation and energy savings

Wastewater treatment conditions are complex, and stable online measurement is the foundation for precise control. New ion-selective sensors and sludge interface measurement support operation control and energy optimization.

Memosens digital electrode CAS41E helps wastewater plants become intelligent, automated, and unmanned: it provides ammonia and nitrate values together to coordinate aerobic nitrification and anoxic denitrification; supports online calibration to reduce field maintenance; gives continuous real-time data for faster process response; ensures compliant discharge; and provides a reliable basis for aeration and recirculation control, cutting energy and operating cost. It supports continuous NH4-N and NO3-N monitoring in biological aeration tanks and in groundwater, well water, and raw water sources exposed to agricultural pollution and environmental change.

Memosens CUS71E sludge interface sensor

CUS71E is Endress+Hauser's latest ultrasonic interface sensor for continuously monitoring sludge blanket level or solid-liquid interface in sedimentation tanks, thickeners, storage tanks, and reservoirs, enabling automated settling control. As the upgrade to Turbimax CUS71D, it improves measuring range, diagnostics, commissioning convenience, maintenance, and digital capability. It is widely used in municipal wastewater plants, waterworks, mine thickeners, tailings ponds, and hydraulic sand basins. In secondary clarifiers, sludge blanket thickness must stay within range: too thick and settled sludge is re-suspended; too thin and treated water returns to the aeration tank with the return sludge. In thickeners and waterworks flocculation, interface measurement precisely controls sludge discharge and lowers water content.

From a single measuring point to a complete analysis system

Complex liquid analysis often needs more than one accurate instrument: sample pretreatment, installation, cleaning, calibration, data management, and maintenance. By combining analyzers, pretreatment, mounting brackets, automatic cleaning and calibration, and a digital management platform, Endress+Hauser keeps improving complete solutions to make process control more stable and reliable — from a single measuring point to a whole analysis system, and from product selection to application support.

Conclusion

From product innovation to industry application, and from measurement upgrades to digital management, Endress+Hauser will keep responding to customer needs in measurement, operation, and maintenance, supporting smart water services, green industry, and sustainable development with reliable measurement.
