The instrument used to measure oxygen consumption was a VOLUMETER. This device can be used to measure the concentration of oxygen consumption over time.
The volumeter is a device that can be used to measure the changes in volume represented by the movement of an air bubble in a capillary tube.
In consequence, this dispositive enables the detection of small changes in volume that result from the exchange of gases (i.e., oxygen and carbon dioxide) during plant photosynthesis or respiration.
A volumeter device is said to be a closed system because it works in controlled conditions.
