How To Ensure Accurate And Successful BOD Measurements

YSI created this document to address some common problems that are encountered when conducting Biochemical Oxygen Demand (BOD) testing. There can be confusion about BOD and its relationship with dissolved oxygen (DO) readings. Even though the end result of BOD testing is a final BOD reading, the calculations are all based on DO readings. Therefore, DO readings must be as accurate as possible to ultimately get accurate BOD results.

YSI has been a leader in the field of DO measurements for 55+ years. Several of YSI’s BOD probes incorporate the Clark Polarographic, membrane covered, sensor  technology (some Model numbers include the 5905, 5010, 200-BOD, ProBOD and 5750) while the YSI ProOBODTM uses a membrane-less optical DO technology.
