Biological stability – DRI RESPIROMETER
Want to verify that organic materials have been sufficiently treated for safe disposal, composting, or beneficial reuse?
The ECHO Instruments adiabatic respirometer supports the assessment of the biological stability of waste, sludge, compost, and other organic materials through the determination of oxygen consumption. The method involves continuously measuring the oxygen consumed during the oxidation of biodegradable organic matter under controlled forced-air conditions.
The automated system provides continuous O₂ measurement, controlled airflow, and reproducible test conditions, enabling reliable evaluation of microbial activity and biological stability.
