GB/T 20245.4-2013 "Expression of performance of electrochemical analyzers - Part 4: Dissolved oxygen in water measured by membrane covered amperometric sensors"

GB/T 20245.4-2013 Focused electrochemistry analyzer performance representation, specifically for the measurement of dissolved oxygen in water by film laminating current-type Sensors. The standard specifies the Measurement principle and describes the structure and working characteristics of Sensors. Detailed measurement system performance indicators, such as Measurement range, Precision, Response time, etc. It also specifies instrument calibrating, measurement operation flow, data processing, etc., providing standard methods for accurate determination of dissolved oxygen in water, and assisting water quality monitoring. It is widely used in environmental protection, water conservancy and industrial water testing.
