There are two main types ofdissolved oxygensensors:optical(luminescent) and Clark electrochemical (membrane covered electrode oramperometric). These main types have subtypes, slightly differing from each other, see figure 1. Figure 1. Diagram ofsensortypes. Source: [6] Differentsensortypes suit some applications better than the others

Oxygensensors and transmitters are used in many industries such as water, wastewater, chemicals, power, life sciences, pharma, food & beverage and fish farming. Thesensorselection depends on your preferences:amperometric oxygensensors measure accurately and linearly fromoxygentraces up to highoxygenconcentrations
Read MoreOpticalDOSensor. When anopticalDOsensoris immersed in water sample,oxygencrosses the membrane and interacts with the dye. This quenches or reduces the intensity and lifetime of the dye’s luminescence, which is measured by the photodetector and used to calculate the DO concentration
