Description

technical field [0001] The invention relates to a precise liquid-taking and measuring device for a water quality analyzer, belonging to the technical field of precision liquid-taking and measuring devices. Background technique [0002] The discharge of various wastewater is the main source of serious pollution of surface environmental water. Therefore, it is necessary to monitor the wastewater discharged from pollution sources, control the total amount of wastewater discharge, and protect the water environment on which human beings depend. At present, the pollution source wastewater monitoring network established for real-time monitoring of various pollution source wastewater is gradually taking shape. Such a pollution source wastewater monitoring network system consists of a sewage discharge monitoring sub-station, a monitoring central station and a management center. The sewage discharge monitoring sub-station is the key to the entire monitoring network system. It is resp...
