1、 Product Overview:

YGDM-TNThe total nitrogen online monitoring system is an online monitoring instrument used for the total nitrogen index of surface water and discharged sewage. The instrument is based on national or industry standards and has the characteristics of simple operation, high degree of automation, easy maintenance, and low cost of consumables. The instrument comes standard withRS485/RS232Interface, supportsMODBUSThe protocol can comprehensively grasp its operation status and data through remote communication, and can also be remotely controlled to achieve advanced functions such as remote analysis, remote calibration, and remote cleaning. In addition, the instrument comes with a dilution function, which can also meet the application requirements for high concentration samples. After long-term feedback verification, the accuracy and other indicators of its analysis are superior to the relevant national standards.

This analyzer is capable of long-term unmanned automatic continuous operation according to on-site settings, and is widely applicable to industrial pollution source discharge wastewater, municipal sewage treatment plant wastewater, environmental quality surface water and other occasions. According to the complexity of the on-site testing conditions, corresponding preprocessing systems can be selected to ensure the reliability of the testing process, accurate testing results, and fully meet the on-site requirements of different occasions.

This product is suitable for: surface water, domestic sewage, industrial wastewater, etc.

Method basis:

Determination of total nitrogen in water quality - Alkaline potassium persulfate digestion UV spectrophotometry methodHJ 636-2012

Technical requirements for total nitrogen water quality automatic analyzerHJ/T 102-2003

2、 Product principle:

In the presence of potassium persulfate, nitrogen-containing compounds in the water sample undergo high digestion and are completely converted into nitrate nitrogen. After cooling to room temperature, they react with the indicator to form a colored complex. The analyzer detects the color change and converts it into the total nitrogen value for output. The amount of colored complex generated is equivalent to the total nitrogen content.

This method is applicable to total nitrogen in0~100mg/LWastewater within the range, excessive calcium and magnesium ions, residual chlorine, or turbidity may interfere with the measurement.
