Field of application
Liquiline System CA80CR offers highly accurate online measurement for optimized chromate removal in industrial wastewater. It supports you in achieving environmentally compliant electroplating and tanning processes. Like all Liquiline System analyzers, CA80CR enables plug & play of up to four Memosens sensors - minimizing the installation effort. Automatic calibration and cleaning plus advanced diagnostics with remote access ensure consistent process safety.
Liquiline System CA80CR supports you in improving the environmental performance of your processes by:
- Monitoring and optimizing the cleaning capacity of industrial wastewater treatment plants. 
- Effluent monitoring in tanneries and electroplating plants. 
- Monitoring of membrane filtration. 
- Limit monitoring in drinking water applications. 
Benefits
- Standardized colorimetric measuring principle - diphenyle carbazide method - guarantees compliance with discharge regulations. 
- Reduced operating costs through automatic calibration and cleaning and low reagent consumption. 
- Simple maintenance: no tools required. 
- Advanced diagnostics with remote access for increased process safety. 
- 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. Reduces installation effort.
