The GASDNA DA-750-O2 is a trace oxygen analyzer designed for continuous monitoring of low-level oxygen concentration in hydrogen and industrial process gases.

With a measuring range of 0–1,000 ppm, the analyzer enables precise monitoring of trace O₂ where oxygen concentration is an important parameter for process control, gas purity and quality management.

The suction-type design continuously draws sample gas from the process for real-time measurement and can be integrated with process monitoring and control systems through 4–20 mA output and optional RS-485 Modbus communication.

The DA-750-O2 is suitable for hydrogen production and purification processes, inert gas systems and other industrial applications requiring continuous trace oxygen monitoring.
