Respirometer ER series

System for measuring CO₂ production in the process of biodegradation to determine biodegradability of the sample

Respirometer is a device that measures the respiration of living organisms. Respirometer determines the aerobic or anaerobic biodegradability of solid, liquid and algae samples in various applications. The system measures the concentration of O₂ and CO₂ in the flow through the sample under controlled conditions. Flow, temperature, pressure, humidity are also continuously measured. Software automatically calculates CO₂ production and % biodegradation. Additional gases can also be measured.
