Online total nitrogen analyzer
Wtf2000-tn water quality analyzer is an on-line monitoring instrument for total nitrogen index of surface water and sewage. The instrument is based on the national standard or industry standard. It has the characteristics of simple operation, high degree of automation, easy maintenance and low cost of consumables. The instrument is equipped with RS485 / RS232 interface and supports Modbus protocol. It can comprehensively master its operation status and data through remote communication, and can also carry out remote control to realize remote analysis, remote calibration, remote monitoring and control Remote cleaning and other advanced functions. In addition, the instrument has its own dilution function, which can also meet the application requirements for high concentration samples. After a long time of feedback verification, the accuracy of the analysis and other indicators are better than the relevant national standards.
This product is suitable for: surface water, domestic sewage, industrial wastewater, etc.
