Overview Of WDet-5000TPN Total Nitrogen Online Automatic Analyzer
WDet-5000TPN is a self-developed total nitrogen online monitoring analyzer.
This total nitrogen analyzer is based on the global initiative magnetic
conductivity measurement platform, combining with constant optical fiber and
digestion colorimetric integration technology. The total nitrogen automatic
online monitoring analyzer has features including high precision, low detection
limit, high stability, and low maintenance frequency.

This total nitrogen analyzer 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 Of WDet-5000TPN Total Nitrogen Online Automatic Analyzer

High accuracy and reliability, strong capability of anti-interference
● Magnetic conductivity measurement technology used on total nitrogen analyzer
will be not affected by chromaticity, suspended
solids and bubbles, especially suitable for the monitoring of inlet water
● The total nitrogen analyzer's special design of flow and reagent ratio, high
precision, low detection limit(0.2mg/L)
