The water quality detection not only needs high-level analytical instruments, but also puts forward higher requirements on links such as water quality sampling, and the like, particularly analyzes water quality data on line in real time, acquires pollution factors in time, analyzes and traces the source, and is very important for avoiding secondary pollution, mastering dynamic change of water resources and improving utilization efficiency of the water resources. The research of the water quality detection method is not only an important basis for developing and using water resources and an important basis for preventing and treating water pollution, but also an effective means for protecting water environment and an important means for promoting the sustainable development of social economy, and has relatively important research significance and application value.

The automatic water quality water sample sampling sampler is mostly installed at a pollution source, and is generally matched with an online monitoring instrument for use due to water sample collection, so that the sampling in a timing, quantitative and equal proportion manner is realized, and the water sample collection is automatically completed. After sampling is finished, samples are manually extracted, and laboratory analysis is carried out, so that monitoring data of all pollutants can be finished. The water sample is extracted into the sample reserving device at regular time through the water taking pump, and various online instruments obtain water samples from the sample reserving device. And can measure the water intaking volume, before mixing the sampling at every turn, all can judge the intake liquid level to can indicate and record no water and report to the police.
