If the water quality monitor wants to work properly, its monitoring system must be indispensable. Then some people will ask, as the problems in all aspects of the instrument accessories are understood, then whether this monitoring system will not go wrong? Not so, many things are not we can calculate accurately, can only say to prevent the occurrence of things!

This chapter water quality online monitoring instrument manufacturers to understand the problems in the use of water quality online monitoring system:

· When it comes to the instrument, its reliability is difficult to guarantee. The correction has been adjusted before use, but there may be errors in the working process, and then affect the accuracy of the value, which makes the monitoring personnel very headache.

· At present, the online monitoring instrument configured by the system is relatively speaking, there are not many manufacturers engaged in the production of this online monitoring instrument in China, and some of them are imported. In this way, the cost of maintenance will be relatively high, especially imported parts, and the operation skill requirements of maintenance personnel will be relatively high.

· Most of the instruments are in direct or indirect contact with sewage, and the requirements for the cleaning work of the instruments will be relatively high. Without regular cleaning of the instruments, it is likely to produce detection errors in the long-term operation process, affecting the accuracy of big data!

· Some sewage plant testing system instrument configuration does not meet the needs of high-level system automation, such as the number of monitoring equipment is not enough, equipped with insufficient functions and other factors, need manual inspection to increase the safety factor of monitoring operation.
