In order to ensure the safety of water quality, it is necessary to monitor the water quality. So where do you start to ensure the reliability of water quality monitoring? This chapter water quality online monitoring instrument manufacturers to understand water quality monitoring problems with you!

Learn Why Water Quality Should be Monitored? What is the Purpose of Monitoring?

After the polluted water quality is monitored, the water quality parameters are not exceeded and then discharged. In this process, it is necessary to carry out real-time monitoring of the water quality through the water quality monitoring instrument, monitor the types of pollutants in the water, the solubility and change trend of various pollutants to evaluate the water quality. The purpose is to monitor groundwater, process water, surface water and other water sources, monitor whether the parameters in the water body exceed the standard, and then treat it, and then discharge it after treatment! Therefore, it is necessary to monitor the water quality.

How to Ensure the Reliability of Water Quality Monitoring?

First, it is necessary to understand what pollutants are contained in the water, and then install water quality online monitoring equipment with different parameters according to the needs for corresponding data monitoring. In order to ensure that the data can accurately reflect the situation of the water environment, from the perspective of quality assurance and quality control, it is required that the monitoring data of the replacement machine is representative, accurate, precise, and comparable. Accuracy and precision are inherent properties of the analysis results to be monitored, so it must be implemented correctly according to the characteristics of the method used.

We know that it is generally characterized by the accuracy of the monitoring data. It is often used to measure the degree of agreement between the results obtained by a particular analysis program and the assumed or accepted truth value. The accuracy of an analysis method or analysis system is a comprehensive index that reflects the systematic errors or random errors existing in the method or the measurement system, which determines the reliability of the analysis results! Accuracy is expressed by absolute error or relative error!
