What is the advised gas flow rate for most analyzers during calibration?

The advised gas flow rate for most analyzers during calibration is 2 liters per minute. This flow rate is generally recommended because it provides a sufficient volume of gas to accurately allow the analyzer to respond and adjust to the nitrogen and oxygen levels present in the mixture being tested. Utilizing this flow rate optimizes the analyzer's response time, ensuring that it can effectively detect and display accurate readings without being affected by potential fluctuations in gas concentration that might occur at higher or lower flow rates. Operating at this recommended rate helps maintain consistency in measurements and enhances the reliability of the calibration process, ultimately contributing to safer diving practices.
