• HQD benchtop multi meters may also be available for specialists who need a focused lab meter just for any software.
Oxygenation: Any exposure with the sample to atmospheric oxygen throughout the BOD test may lead to oxygen transfer, influencing the calculated dissolved oxygen ranges. It's critical to make sure the airtight sealing of BOD bottles to circumvent oxygen Trade.
BOD measurements can come upon numerous troubles that could affect the precision and reliability of the final results.
