TGH-STN Total nitrogen water quality on-line automatic monitor

Instrument is introduced

 

The total nitrogen content in water is one of the important indexes to measure water quality. The determination is helpful to evaluate the status of water pollution and self-purification. When the nitrogen and phosphorus in the surface water exceed the limit, the microorganisms multiply in large quantities, and the plankton grow vigorously and appear eutrophication. Tgh-stn total nitrogen water quality online automatic monitoring instrument is based on the world's first magnetic conductivity measurement platform, combined with constant temperature optical fiber, digestion colorimetric integration technology, to achieve high precision, low detection limit, high stability and low maintenance of total nitrogen automatic online monitoring.

 

The working principle of the product conforms to the technical requirements of "GB 11894-1989 water quality determination of total nitrogen - alkaline potassium persulfate digestion uv spectrophotometry". The spectrophotometric measurement method can automatically and continuously work according to the long-term unattended field setting. According to the complexity of the field test conditions, the corresponding pretreatment system can be selected to ensure the reliable test process, accurate test results and meet the requirements of different occasions.
