Geotech Biogas 5000 Portable Gas Analyser

The Geotech Biogas 5000 is suitable for monitoring biogas in farming, wastewater, and food processing sectors or for CH4 recovery and hazardous anaerobic digestion sites.

Helping you gauge the efficiency of your digestion process so gas levels can be changed for optimum performance.

An anemometer does not need to be self-certified; the Biogas 5000 validates results in conformance with PPC (Pollution Prevention and Control). The unit can be configured according to the user’s specifications.

A portable, durable detector with an internal pump powered by a rechargeable battery, allowing 8 hours of use from a full charge. Designed to be easy to use, maintain and calibrate.
