YSI 5000 DO Meter

Ease of use, data integrity, expanded range, enhanced digital capabilities – the YSI 5000 Series is engineered to meet the need of highly accurate, reliable dissolved oxygen measurements, primarily to determine BOD, Oxygen Uptake Rate (OUR) and Specific Oxygen Uptake Rate (SOUR).

The YSI 5000 features menu-driven operation and a large liquid crystal display. Internal memory for 100 data sets with date/time stamp eliminates the need for manual entry of readings. An RS-232 interface allows upload to spreadsheets. Multitasking is enhanced with the auto-stabilization capability, which enables you to predetermine a stable reading and be alerted to that condition.
