WDet-7000 TPN Total Phosphorus Online Analyzer
WDet-7000TPN Total Phosphorus Online Analyzer is developed based on the global initiative magnetic conductivity measurement platform, combining with constant optical fiber and digestion colorimetric integration technology. The analyzer has the features, including high precision, low detection limit, high stability and low maintenance frequency. This total phosphorus analyzer works in accordance with the technical requirements of GB 11893-1989 Water Quality Total PhosphorusAmmonium Molybdate Spectrophotometry, fully meets the pollution sources, municipal wastewater, industrial processes in the application areas and has passed the certification of CCEP
Features:
High accuracy and reliability, strong capability of anti-interference
• Magnetic conductivity measurement technology, not be affected by chromaticity, suspended solids and bubbles, especially suitable for the monitoring of inlet water
• Special design of flow and reagent ratio, high precision, low detection limit(0.1mg/L, even 0.01mg/L)
• Constant optical fiber and light intensity compensation algorithm, small drift for long-term operation
Low maintenance and cost
• Self-checking function, easy to debug, maintain, comparison test
• Self-diagnosis function, assisting maintainer to analyze the failure
• Imported single-channel high integration valve island, simple and easy to maintain, dismantle and clean
• All-day networking for real-time inspection of instrument running state
High intelligent level
• Scan code function: rapidly obtain running/maintenance information of the instrument
• Alarm function: this analyzer provide intuitive and accurate information for grounding self-check, reagent insufficiency and etc
• Great quality control: equipped with parallel sample test, standard sample verification and standard recovery rate detection
• Reverse control function: start automatically by flow and PH
