With Aquaview, Christ offers a monitoring and evaluation system for water-treatment plants. Based on a special software which is integrated into the user interface, this system permits the implementation of comprehensive recorder functions as well as data acquisition, archiving and evaluation. Remote operation of the plant is also available as an option. The standardized user interface permits easy operation and also improves the reliability by external data evaluation and early detection of faults. The in-house costs for operation and maintenance of the pure water system are reduced. Up to 520 million records can be saved on currently available memory cards.
