When environmental inspection and law enforcement personnel are conducting water quality sampling in special environments such as sewage wells, manholes, and rainwater pipelines, due to the small and enclosed space, personnel cannot directly enter the space for sampling. The existing sampling buckets and bottles cannot achieve automatic collection of water samples, which brings great inconvenience to water quality monitoring. By analyzing the water quality of rainwater pipe network samples, it is possible to determine whether there is a direct discharge of sewage into the rainwater pipe network in an area. Therefore, it is particularly important to obtain representative water samples to judge the results. Through a deep understanding of this reality and years of experience in developing water quality samplers, Qiheng Environmental Protection has launched a water sample collection system that can be unmanned and automatically collected according to the set programHX-B Multi Field Water Quality Automatic Sampler.

The sampler can perform timed and quantitative water sample collection, and the sampling method can be set to single bottle, single sample, or multiple single bottles. It is equipped with a 2L large capacity sample bucket, which facilitates the detection and analysis of multiple water quality indicators in one sampling.

A third-party testing company was commissioned by a certain location to conduct testing and analysis on water samples from rainwater wells in the rainwater pipeline network, in order to determine whether there is a direct discharge of sewage and wastewater from surrounding enterprises in the pipeline network. In the past, the third-party testing company usually conducted timed manual sampling, and the samples taken were usually water samples flowing through rainwater wells at a fixed time, which did not have representative significance for the entire process.

After multiple communications with our sales and technical personnel, the third-party testing company confirmed the functional characteristics of the sampler and applied it to the water quality testing project of the rainwater well. The staff set the sampler to automatic timed quantitative single bottle diversified sampling mode during sampling, and placed it in the well for 24 hours for water sample collection, ultimately obtaining satisfactory and representative samples.
