▎Product Introduction ：
Studies indicate 1% H₂ purity reduction causes 11% efficiency loss. Impurities (O₂/N₂/CO₂) create safety hazards. H₂ explosion range: 4.1%~74.2% in air (H₂/O₂ mixture).
The RA1630B enables real-time O₂ monitoring in hydrogen-cooled generators for operational safety.
▎Key Features ：
1.Intrinsically safe explosion-proof sensor.
2.High accuracy with anti-interference.
3.Automatic drainage system.
4.On-site calibration capability.
5.Sensor protection technology.
