In this workshop, you will gain an understanding of several different types of dissolved oxygen sensors available for groundwater sampling and monitoring applications. The sensor options include steady-state electrochemical—both polarographic and galvanic, rapid pulse polarographic, and optical. Each sensor type detects dissolved oxygen using different methodologies. Therefore, there are advantages and disadvantages associated with each sensor. An understanding of how these sensing methods differ can help determine the option best suited for a particular application.
