WDet-7000 Ammonia Nitrogen Online Analyzer
WDet-7000 Ammonia Nitrogen Online Analyzer is develped based on the global initiative magnetic conductivity measurement platform, combining with constant optical fiber and digestion colorimetric integration technology. The ammonia-nitrogen analyzer has the features, including high precision, low detection limit, high stability and low maintenance frequency. This ammonia-nitrogen analyzer works in accordance with the technical requirements of HJ/T 536-2009 Water Quality Ammonia-Nitrogen Measurement-Salicylic Acid Method, fully meets the pollution sources, municipal wastewater, industrial processes in the application areas, and has passed the certification of CMC and 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
• Strong anti-interference ability to color resistance and calcium and magnesium ion
• Special design of flow and reagent ratio, high precision, low detection limit(0.01mg/L)
• Constant optical fiber and light intensity compensation algorithm, small drift for long-term operation
Easy operation & Low maintenance
• Self-check 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 the analyzer
• Alarm function: this analyzer provides intuitive and accurate information for grounding self-check, reagent insufficiency and etc
• Great quality control: equipped with a parallel sample test, standard sample verification, and standard recovery rate detection
• Reverse control function: this analyzer starts automatically by flow and PH
