How important is the regular maintenance of online water quality testing equipment?

Online water quality testing instruments such as COD analyzer, ammonia nitrogen, and heavy metal analyzers are responsible for ensuring the safety of water quality, and to ensure that the water quality online monitoring instrument achieves long-term operation to ensure the usefulness of the data, then it is time to protect the online water quality testing instrument Very necessary.

The necessity of timing protection of online water quality testing equipment:

There are many factors that affect the monitoring data of online water quality testing instruments, such as water collection and distribution, instrument operation, reagents, and standard solutions, etc., but in practice, if you can conduct targeted and correct online water quality monitoring The protection and management of the instrument can still effectively improve the accuracy of instrument monitoring and make its data representative.

Therefore, the correct protection method of water quality online monitor is a crucial step to determine the accuracy, precision, representativeness, completeness, and comparability of monitoring data.

The timing protection of the online water quality testing instrument should be started from three aspects. The first is the timing verification of the online Water quality monitoring instrument. The intention is to ensure that the instrument can still maintain its superiority even when the instrument is adjusted and used from the beginning. Performance to prevent inaccurate measurement data caused by the instrument;

The second is the multi-point linearity test of the instrument. Basically, the multi-point linearity test of the standard curve of the instrument is usually done once every six months to ensure that the instrument is in excellent operating condition;

The third day is aimed at the impact of the detection environment on the water quality online monitor. Because the environment where the water quality online monitor is located is relatively harsh, the sediment will cause the sensitivity of the sensor to change, which will make the detection and analysis of the water quality online monitor determine The results produced errors, so it is necessary to clean the online water quality monitor regularly to keep it in an outstanding condition.

Doing a good job in the regular protection operation of online water quality testing equipment can assist in scientific and useful water quality monitoring operations, timely grasp the water quality status, and achieve the purpose of effectively controlling pollution, qualified discharge, and improving water quality. It can be said that monitoring instruments and related skills are the pillars of building a comprehensive, all-weather, three-dimensional environmental monitoring network system, and have played the role of a national pillar in my country's environmental monitoring and protection operations.
