ECHO ER Series multichannel respirometer for biodegradability testing
ECHO ER Series is a modular multichannel system for online monitoring of CO₂ production, O₂ consumption and percentage biodegradation in solid, liquid or algae samples.
The system continuously tracks gases and process conditions including flow, temperature, pressure and humidity. Configurations from 12 to 60 channels suit certification laboratories, material producers, universities and research centres. The 2026 software supports flexible channel management, live parameter changes, guided alerts and multiple experiments on one platform.
