Ammonium analyzer Liquiline System CA80AM

Regulation compliance meets ease of use

Endress+Hauser launches a new colorimetric analyzing system for ammonium. Liquiline System CA80AM and its sample preparations are fit for all critical control points of water and wastewater treatment. They are the start of a new analyzer platform combining high precision with easy operation and maintenance.


  • Fast commissioning and plug & play thanks to Memosens technology and user-friendly operation

  • Easy upgrade of functionality - even to a complete measuring station - simply by adding modules and connecting Memosens sensors

  • Advanced diagnostics with remote access for increased process safety

  • Reduced operating costs through automatic, configurable calibration and cleaning and long reagent shelf life with optional cooling module

  • Compliance with standard colorimetric measuring principle - indophenol blue method - following ISO 7150-1, DIN 38406-5 and GB 7481-87

Precise as laboratory equipment but online

Liquiline System CA80AM uses the indophenol blue method, the standard colorimetric measuring principle. This gives plant managers the security of highly precise ammonium measurement at all critical control points of the wastewater treatment plant. Compared to laboratory measurements, however, the online Liquiline system CA80AM delivers values much faster which enables a quick reaction to varying ammonium loads at the inlet and fine-tuning of the blower systems in the aeration basin.

Reduced complexity of instrumentation

Liquiline System shares the platform’s user-friendly operation that plant personnel already knows from other online analysis parameters such as pH or conductivity. The platform concept makes it possible to upgrade the analyzer to a measuring station simply by connecting Memosens sensors. Memosens technology also enables plug & play and allows full control of the sample preparations by the Liquiline System CA80AM analyzer, speeding up commissioning and operation.

Sampling right to the point

Liquiline System CAT820 is the standard solution for the aeration basin or the outlet that can be flexibly adapted to any wastewater treatment plant. Cost efficient sample preparation in the outlet or in pressurized pipes is done by Liquiline System CAT810 that reflects process changes promptly and shortens the response time of downstream measuring devices.

Low consumption and simplified maintenance

Operating costs of a colorimetric analyzer stand and fall with the reagent consumption. That’s why Liquiline System CA80AM is designed with ultra-precise dispensers for reagent dosing and an intelligent cooling system. This guarantees reduced consumption and a reagent lifetime of up to three months. Automatic cleaning and calibration functions ensure that the analyzer and its sample preparation work reliably and without manual intervention over a long period of time.
