Why doesnt the BODTrak II give me the same results as the BODTrak?
The BODTrak was developed at a time when respirometry was not widely used as a standalone technique for measuring BOD. Hach designed the BODTrak to allow for directly comparable results with the dilution method after a 5-day incubation period. With the recent acceptance of the Respirometric Method 5210 D by Standard Methods, improvements were made to allow for greater precision and accuracy and alignment with the new method.
