Do you have a need for Biological Oxygen Demand (BOD) testing? Oxi700™ Respirometric BOD System is available here at AquaOnDemand.com.

Respirometric methods provide direct measurements of the oxygen consumed by microorganisms from an air or oxygen-enriched environment in a closed vessel under conditons of constant temperature and agitation.  Carbon dioxide produced metabolically by the bacteria is chemically bound by the potassium hydroxide solution contained in the seal cup in the bottle.  The result is a pressure drop in the system which is directly proportional to the BOD value and is measured by the BOD sensor. The BOD level is then displayed in mg/l.
