The GASDNA DA-600-O2 is an explosion-proof, diffusion-type oxygen gas detector designed for continuous monitoring of oxygen concentration in industrial and hydrogen-related facilities.

With a measuring range of 0–25 %Vol, the detector provides real-time O₂ concentration monitoring and two-stage alarm outputs, helping detect oxygen deficiency or abnormal oxygen conditions and maintain a safe working environment.

The DA-600 supports 4–20 mA output for integration with PLC, DDC and centralized gas monitoring systems. RS-485 Modbus and HART communication are also available as options.

Its robust explosion-proof design makes it suitable for hydrogen production facilities, electrolyser systems, gas storage and supply areas, and other industrial locations requiring continuous oxygen monitoring.
