A reading of 652 on register 40001 equals 65.2% CH₄.
MethaMeasure has emerged as a critical tool in the anaerobic digestion (AD) and biogas upgrading industry. Designed for continuous, real-time monitoring of methane (CH₄), carbon dioxide (CO₂), and hydrogen sulfide (H₂S), this device ensures your biogas plant operates at peak efficiency while adhering to environmental regulations. methameasure user guide
