YSI Pro Digital Pro Solo Handheld Monitor 

Introducing the ProSolo DIGITAL handheld, YSI’s most advanced Optical Dissolved Oxygen (ODO) field meter. The ProSolo benefits from years of expertise in cutting-edge dissolved oxygen technology.

Featuring expanded measurement capabilities with ODO/T (Optical Dissolved Oxygen/Temperature) and ODO/CT (Optical Dissolved Oxygen/Conductivity & Temperature) probe options, the ProSolo is ideal for a variety of applications including aquaculture, coastal, estuary, and wetland sampling.

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

Utilizing the most advanced DO sensing technology, the ProSolo incorporates smart sensor technology that enables sensors to be automatically recognized by the handheld. Additionally, Pro Digital sensors store calibration data, so probe assemblies can be swapped between handhelds without the need for re-calibration.
