The ProSolo DIGITAL handheld replaces the ProODO® as YSI’s most advanced optical dissolved oxygen field meter. Paired with the latest optical DO and temperature (ODO®/T) probe, the ProSolo benefits from years of expertise in cutting-edge dissolved oxygen technology.

ProDIGITAL Platform for enhanced versatility. Connect any ProDIGITAL integrated probe/cable assembly the ProSolo to form a complete sampling system. Probe assemblies are user-replaceable with cable lengths ranging from 1 to 100 meters. 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 a higher accuracy with no stir dependence, less drift over time; holds calibration longer,less maintenance; no membranes or electrolyte, ProDIGITAL Smart Sensors. In addition to utilizing the most advanced DO sensing technology, the ProSolo incorporates smart sensor technology that enables sensors to be automatically recognized by the handheld. Additionally, DIGITAL sensors store calibration data, so probe assemblies can be swapped between handhelds without the need for re-calibration.

The optical BOD (OBOD) sensor utilizes EPA approved methODO®logy for wastewater compliance reporting of BOD and CBOD, while ODO®/T probe assemblies utilize EPA approved methODO®logy for compliance reporting of Dissolved Oxygen. The ProSolo handheld meets the demands of true field work with a rugged, waterproof case (IP-67 rated) and a military-spec (MS) cable connector. Rigorously drop tested from all angles, the handheld features a 3-year warranty, while a 2-year warranty is included with the probe assembly and ODO® Cap.
