ProSolo Optical Dissolved Oxygen and Conductivity Meter YSI

Specification of

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
