The quantity of oxygen consumed per unit of time and per unit of volume, called respiration rate (mg/l.h) is one of the most important parameters for the biological activity of activated sludge. Consequently, the determination of the respiration rate is of great importance in gaining insight in activated sludge plants. For the on-line determination of the respiration rate of activated sludge, or any other oxygen consuming liquid the measured values must be available with short intervals, and must be reproducible and of high accuracy. These series of respiration analysers meet these requirements. Every minute, a new value of the respiration value is available. There are several versions available to fully meet your needs: on-line and a laboratory version (batch).
