Overview
WDet-5000TPN is a self-developed total nitrogen online monitoring instrument. This product is based on the global initiative magnetic conductivity measurement platform, combining with constant optical fiber and digestion colorimetric integration technology. The total nitrogen in wastewater effluent automatic online monitoring system has features including high precision, low detection limit, high stability, and low maintenance frequency.
This product works in accordance with the technical requirements of GB 11894-1989 Water Quality Total Nitrogen-Alkaline Potassium Persulfate Digestion-UV Spectrophotometry, fully meets the pollution sources, municipal wastewater, industrial processes in the application areas, and has passed the certification of CCEP.
Features Technical Specification
Features Of WDet-5000TPN Total Nitrogen Online Automatic Analyzer
High accuracy and reliability, strong capability of anti-interference
