PWQ-2000
PROBEST
Features
l Integrated design, save space
l The internal wiring and waterway are highly integrated, and users only need to connect the power supply and enter and exit the water.
l The internal waterway design can try to ensure that the water flow is stable during the internal measurement process of the equipment, and ensure the monitoring data is accurate;
l DPD colorimetric analyzer, with automatic cleaning function, reducing maintenance
l With 7-inch color touch screen, the operation interface is simple, easy operation, reliable system, low maintenance
l With data storage and curve display functions, master the dynamic changes of water quality;
l With automatic fault diagnosis function, abnormal information recording and uploading functions, such as parts failure, over-range alarm, over-standard alarm and other information;
l With three-level management authority;
l Historical data download and curve display can intuitively and accurately understand and track the changes of water parameters within a certain period;
l Optional wireless data transmission module.
l Applications
l Water quality monitoring of waterworks and water supply network
l Detection of water quality standards for secondary water supply in the community
l Real-time water quality monitoring of swimming pool, SPA, etc.
l Rural tap water quality monitoring
