The GASDNA DA-770-CH4 is a process gas analyzer designed for continuous measurement of methane (CH₄) concentration in industrial and hydrogen-related processes.

Using NDIR (Non-Dispersive Infrared) technology, the analyzer provides reliable and stable CH₄ measurement over a range of 0–100 %Vol.

The DA-770-CH4 is suitable for process monitoring applications such as hydrogen production, reforming processes, gas purification systems and other industrial processes where continuous methane concentration measurement is required.

For reliable process measurement, the analyzer can be integrated with a sampling and conditioning system to maintain appropriate sample flow and remove moisture or particles where required.
