Description

technical field [0001] The invention belongs to the technical field of water quality analyzers, in particular to a portable water quality analyzer. Background technique [0002] Human beings cannot live without water, and the quality of drinking water is closely related to human health. With the development of social economy and the improvement of people's living standards, people's requirements for the quality of drinking water have been continuously improved, and the standards for drinking water quality have also been continuously developed and improved accordingly. Drinking water mainly considers the impact on human health, and its water quality standards include not only physical and chemical indicators, but also microbial indicators; for industrial water, it is considered whether it will affect product quality or easily damage containers and pipelines. Due to the bulky size and heavy weight of the current portable water quality analyzers, most of the water quality anal...

AI Technical Summary

Problems solved by technology

Due to the large size and heavy weight of the current portable water quality analyzers, most of the water quality analysis is carried out in the form of a workstation for sample analysis. There are few practical portable instruments, which makes the operation inconvenient and cannot obtain water quality parameters in time.
