DO Operation: 

BOD Measurement 

XL40 and 60 meters

 

 

To measure BOD, a sample is seeded and incubated in the dark at 20°C for five days. The 
dissolved oxygen concentration is then measured and subtracted from the initial, pre-incubation 
dissolved oxygen concentration. The difference is a measure of the Biochemical Oxygen Demand 
(BOD) of the sample.  

Before measuring BOD, remember to setup your BOD measuring mode parameter from the BOD 
Setup screen. Once the meter is standardized you are ready to measure DO for a BOD 
measurement.
