The YSI Pro20 dissolved oxygen meter is built for dependable DO and BOD measurement in demanding field environments while remaining accurate enough for laboratory testing workflows. Designed with durability and usability in mind, the Pro20 supports multiple dissolved oxygen sensor types and provides fast, stable readings for environmental monitoring, wastewater compliance, and research sampling programs. This handheld meter measures dissolved oxygen and temperature and includes features such as internal barometric pressure compensation and rapid calibration functionality to help users collect high-quality data with minimal downtime. If you select a DO/Temp cable (rather than the self-contained ProBOD probe), you'll also need a DO sensor — sold separately. Compatible Sensors (for DO/Temp cable variants only): Sensor Part # Price 2002 Galvanic DO Sensor 605202 $231.84 2003 Polarographic DO Sensor 605203 $231.84 Purchase compatible DO probes separately on our YSI Pro Series DO Sensors page, or browse the full YSI Parts & Accessories collection for cables and cases.
