BIOGAS 5000 portable biogas analyser and GA3000 fixed biogas analyser for Anaerobic digestion (crop digestion).

It was vital for the customer to know and monitor the CH4, O2 and H2S levels on an ongoing basis; accuracy with those readings was incredibly important.

The BIOGAS 5000 in use

The customer generates CH4 by the anaerobic digestion of crops, then stores and uses the gas in an engine to generate electricity. A minimum level of CH4 is required, and the engine is also set up based on the CH4 level. A maximum level of O2 and H2S is controlled on the system based on the readout from the analyser. via Future Biogas choose the BIOGAS 5000 and GA3000 …
