Scope

This part of GB/T 20245 specifies the performance tests for sensors, analyzers, and electronic units used to determine the dissolved oxygen content in aqueous solutions, as well as the requirements, terms, and definitions proposed by the manufacturer.
This part is applicable to analyzers that use film-coated amperometric sensors to continuously monitor the partial pressure or concentration of dissolved oxygen, and also to analyzers used to measure dissolved oxygen in drinking water, water used in industrial processes, industrial wastewater, domestic wastewater, and storage tanks (such as lake water, river water, and harbor water).
The discussions on analyzers using film-coated amperometric sensors are not entirely applicable to non-film-coated electrochemical sensors, but they can be used as general reference materials.
