The RITTER Biogas Batch Fermentation System (BBFS) allows the world-wide unique combination of:
- biogas fermentation tests
- data acquisition of volume and flow rate
- gas analysis of CH₄ and CO₂ as an option
… from up to 18 gas sources.
For this purpose, 9 high-precision RITTER »MultiGas« NDIR (non-dispersive infrared) Sensors are installed in one casing. Up to 2 casings can be attached to the rack the Biogas Batch Fermentation System (BBFS), enabling the analysis of biogas and many other gases in research and development labs.
V 1.0 / Rev. 2024-09-05 / Subject to alterations.
