• Measures % CH4 CO2 and O2 concentration static differential and barometric pressures
• Measures additional gases with optional gas pods
• Reads gas temperature with optional temperature probe
• ATEX certified
• Easy field calibration by user
• Limited Storage

The Biogas Check allows methane producers to be much more in control and able to manage gas production quality. If a digester is producing low quality gas its management can be altered to produce methane-rich gas. Gas analysis during a production run is very important to achieve the valuable high percent methane gas output necessary to justify the investment in a digester and associated equipment and the work of loading and running one.
