VELP RESPIROMETRIC Sensor System 6 - BOD Meter

The compact, reliable, cloud-enabled solution for BOD determination and aerobic respirometric tests.

Biochemical Oxygen Determination BOD

The VELP RESPIROMETRIC Sensor BOD is designed to provide a smart and cloud-enabled solution to laboratories of water and wastewater quality control.

BOD (Biochemical Oxygen Demand) Determination is a simple and easy way for monitoring the microorganisms’ activity in water samples with extremely reliable results.

In particular, microorganisms present or inoculated in a water sample containing biodegradable organic substance, consume oxygen for their metabolic activity and produce a corresponding volume of carbon dioxide.

The carbon dioxide gets absorbed by a strong alkali positioned in the neck of the bottle. The result of this process is a decrease in gas pressure. The BOD measures this change in gas pressure between the beginning to the end of the analysis and gives a result expressed in mg/l .
