Scope: This part of GB/T 20245 specifies the performance tests of sensors, analyzers and electronic units used to determine the dissolved oxygen content of 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 content of dissolved oxygen. It is also applicable to measuring drinking water, industrial process water, industrial wastewater, domestic wastewater and storage tanks (such as lakes, rivers, harbors, etc.) Analyzer for dissolved oxygen in water). For the discussion of analyzers using coated amperometric sensors, it is not fully applicable to uncoated electrochemical sensors, but can be used as a general reference.
