Zetian - Model WDet-7000 -Integrated Water Quality Online Automatic Analyzer

• Using a new measurement technology to solve the problem of inaccurate measurement of watersamples such as large color turbidity, many suspended solids, and many bubbles
• Single-channel highly integrated valve island technology, easy to clean and disassemble, low cost and low maintenance
• Light intensity compensation algorithm, effectively solve the long-term drift problem of field instruments
• Extensible function of over-standard sample retention to retain samples with abnormal data for manual analysis
• Each module has independent sampling, digestion and measurement functions without cross-inter-ference
