Field of application

Liquiline System CAT820 provides clear samples directly from your process. Equipped with Memosens technology, it simplifies commissioning and supports predictive maintenance. Easy cleaning of the special membrane surface and tool-free maintenance reduce your operating costs. CAT820 can be combined with the modular Flexdip holder to facilitate adaption to your process. It is fully controlled by the Liquiline System analyzer, allowing perfect synchronization of your measuring point.

Liquiline System CAT820 is designed for:

Aeration basins and outlets of municipal and industrial wastewater treatment plants
Surface waters
Taking aqueous samples from industrial processes

Benefits

Fast commissioning and plug & play thanks to Memosens technology and user-friendly Liquiline operating concept
Cost-effective through tool-free maintenance and easy replacement of filter elements
Advanced diagnostics with remote access for increased process safety
Optional back-flush function for extended maintenance intervals and minimized effort
Various mounting options for perfect fit to the application
