The GASDNA DA-770-CO2 is a process gas analyzer designed for continuous measurement of low-level carbon dioxide (CO₂) concentration in industrial gas processes.

Using NDIR (Non-Dispersive Infrared) technology, the analyzer provides precise and stable CO₂ measurement over a range of 0–2,000 ppm, making it suitable for applications requiring continuous monitoring of trace CO₂ concentration.

The DA-770-CO2 can be integrated into process monitoring and control systems through its signal outputs and can be combined with a sampling and conditioning system for reliable sample measurement.

Typical applications include hydrogen production and purification processes, process gas quality monitoring, and other industrial applications where low-level CO₂ measurement is required.
