Offers high-precision ammonium measurement in all critical control points. As member of the Liquiline platform, it enables plug & play and easy upgrade to a measuring station - minimising the installation effort. Automatic calibration and cleaning as well as the low consumption of reagents save on operating and maintenance costs. Advanced diagnostics with remote access ensure process safety and support you in providing process documentation to the authorities.

  • 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.
