Product details
Portable Biogas Analyzer - ES 5K (Biogas 5000)

The new generation ES 5K (Biogas 5000) is a new portable biogas analyzer developed by Geotech in the UK to replace the Biogas Check series. It is mainly used for biogas monitoring in biomass anaerobic fermentation projects. The BM 5K (Biogas 5000) is easy to operate and calibrate, and is smaller, lighter, and more precise than the original model. It has international leading technical level and recognition.
