RA1630B Oxygen in Hydrogen Analyzer
Real-time oxygen-in-hydrogen analysis for hydrogen-cooled generator systems and power industry safety monitoring.

Overview
The RA1630B oxygen in hydrogen analyzer is designed for real-time monitoring of oxygen content in generator hydrogen cooling systems. Since reduced hydrogen purity and increased oxygen content can create both efficiency loss and safety risk, the analyzer helps operators maintain safer and more economical operation. It provides accurate oxygen-in-hydrogen monitoring with an intrinsically safe explosion-proof sensing unit.
