The Lovibond^® sensor system BD606 is a 12 sample system that allows precise measurements of BOD based on the manome- tric principle. Manometric respirometers relate oxygen uptake to the change in pressure caused by oxygen consumption while maintaining a constant volume. Due to the modern integral pressure sensors, it is not necessary to use mercury for the measurements.
