Technology of DRI Respirometer determines the current rate of aerobic microbial acvity of solid recovered fuels using the real dynamic respiraon index (DRI).
The current rate of aerobic microbial acvity measures the biological stability under the actual chemical and physical properes of solid recovered fuels.

Principles

DRI Respirometer measures O2 to determine the acvity of microorganisms in degradable  organic maer under defined connuous airflow and adiabac condions. The samples are  measured in hermecally sealed vessels (adiabac), which create controlled condions  determined by EU and other norms.
