Automate the process. The online water quality monitoring system is different from the detection and analysis of water samples in manual laboratories. The environment in which the equipment is located is complex and diverse. The online detection system requires sampling and sample pretreatment devices to have continuous processing capabilities. Because most of the monitoring and analysis instruments are expensive precision chemical analysis instruments, The purity of the sample is very high. Therefore, the system needs to be equipped with a precision filter device for the sample. If the sample contains suspended particles and impurities, it will damage the precision device, increase the failure rate of the system, and reduce the service life of the instrument.
