The YSI ODO/T probe and cable assembly pairs with the ProSolo handheld to form a complete sampling system. Featuring integral, digital sensors, the ODO/T is plug-and-play, which minimizes time spent on instrument setup. Pro DIGITAL technology allows the handheld to automatically recognize connected sensors.

Optical dissolved oxygen (ODO) technology is non-consumptive, meaning oxygen is not consumed during the measurement. Flow dependence is non-existent and no stirring is required, resulting in the most accurate DO measurements available from a probe. The ODO sensor is not susceptible to interferences from other gases, drifts less, and holds calibration longer than membrane-covered sensors. A simple, threaded optical cap contributes to ease of maintenance.
