An evolution of the Professional Series water quality meters, the ProSolo DIGITAL handheld replaces the ProODO as YSI's most advanced optical dissolved oxygen field meter. Paired with the ProDIGITAL ODO/CT (Optical Dissolved Oxygen, Conductivity, and Temperature) probe, the ProSolo is perfect for measuring DO in aquaculture, coastal, estuary, wetland, or any application requiring accurate, real-time salinity-compensated DO measurements.
The ProSolo handheld is the direct replacement to the ProODO Optical Dissolved Oxygen handheld, and is fully compatible with ProODO cables and ProOBOD probes.
ODO® Sensor Technology
Dissolved oxygen measurement technology has advanced from electrochemical sensors, such as polarographic and galvanic, to luminescent-based, optical sensors. YSI optical DO sensors are non-consumptive, meaning oxygen is not consumed during the measurement. As a result, there is no flow dependence or stirring required with ODO, allowing for the most accurate readings in the field.
Advantages over electrochemical sensors include:
Higher accuracy with no stir dependence
Less drift over time; holds calibration longer
Less maintenance; no membranes or electrolyte
