SenseH2-R Hydrogen Sensor (H2 Sensor) Features
• High sensitivity and selectivity to hydrogen
• Fast response and recovery times
• Immune to signal saturation
• Robust to widely varying ambient flow rates
• Compact and rugged design
• 1.0 to 4.5V output, spans 0.25 to 4.0% H2 in air (5 to 100% LFL)
SenseH2-R Hydrogen Sensor (H2 Sensor) Intended Uses:
The NTM SenseH2-R is intended for use as a hydrogen gas detector in the range of 0.25 to 4% hydrogen in air. This sensor is tolerant to halogen gasses commonly found in refrigerant gases and fire suppression systems.
SenseH2-R Hydrogen Sensor (H2 Sensor) Typical applications include:
• Uninterruptible power supply (UPS) systems monitoring,
• Telecom systems monitoring Stationary fuel cells ,
• Laboratory monitoring
• Motive power charging stations
