There are several different types of dissolved oxygen sensors available for groundwater sampling and monitoring. The sensor options include polarographic, galvanic, 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 which sensor is best suited for a particular application. This workshop will explain how each technology measures dissolved oxygen and the advantages and disadvantages associated with each option.
