CODet-7000 COD Water Quality Online Analyzer
CODet-7000 CODcr Online Analyzer is developed based on the global initiative magnetic conductivity measurement platform, combining with constant optical fiber and digestion colorimetric integration technology. This online COD analyzer works in accordance with the technical requirements of HJ/T 399-2007 Water Quality Chemical Oxygen Demand Measurement-Digestion Spectrophotometry. COD measuring equipment has the features of high reliability, low detection limit, high stability, and strong anti-chloride ion interference capability. Now it has been widely used in pollution sources, municipal wastewater, industrial processes, etc. with the certification of CMC and CCEP
Features:
High accuracy and reliability, strong capability of anti-interference
• Magnetic conductivity measurement technology, will not be affected by chromaticity, suspended solids, and bubbles, especially suitable for the monitoring of inlet water
• Special design of flow and reagent ratio, it is high precision, low detection limit (10mg/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 the COD analyzer running state
High intelligent level
• Scan code function: rapidly obtain running/maintenance information of the COD 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 start automatically by flow and PH
