The GASDNA DA-600S-O2 is a high-performance oxygen gas analyzer designed for hydrogen production and process monitoring applications. It provides continuous and reliable measurement of oxygen concentration from 0 to 99.99 %Vol.

Using optical sensing technology, the analyzer provides fast response and stable O₂ measurement. It is particularly suitable for monitoring oxygen concentration in hydrogen production processes where reliable process control and safety monitoring are required.

The DA-600S-O2 supports integration with process control systems through 4–20 mA, RS-485 Modbus, relay outputs and other communication options. Applications include PEM electrolysis, high-temperature electrolysis and other hydrogen production processes.
