WDet-5000 is a self-developed total phosphorus on-line monitoring instrument. This total phosphorus analyzer is based on the global initiative magnetic conductivity measurement platform, combining with constant optical fiber and digestion colorimetric integration technology. The total phosphorus automatic online monitoring system has the features, including high precision, low detection limit, high stability and low maintenance frequency.
This total phosphorus analyzer works in accordance with the technical requirements of GB 11893-1989 Water Quality Total Phosphorus-Ammonium Molybdate Spectrophotometry, fully meets the pollution sources, municipal wastewater, industrial processes in the application areas and has passed the certification of CCEP.
High accuracy and reliability, strong capability of anti-interference
● Magnetic conductivity measurement technology used on ZETIAN total phosphorus analyzer will be not affected by chromaticity, suspended solids and bubbles, especially suitable for the monitoring of inlet water
