4H2-40000 Electrochemical Hydrogen Gas Sensor For Environmental & Equipment Control

Product Applications:

The 4H2-40000 gas sensor is an electrochemical hydrogen (H₂) sensor designed for:

1. Industrial Safety Monitoring
   • Detecting hydrogen leaks in petrochemical plants, refineries, and metallurgical facilities.
   • Monitoring H₂ concentrations in coal mines and fire - fighting scenarios to prevent explosions.
2. Environmental & Equipment Control
   • Used in portable or fixed detection devices for hydrogen - related environmental monitoring.
   • Suitable for hydrogen - powered vehicle systems, fuel cell stations, and laboratory gas safety checks.
3. Wide - Range Sensing
   • Ideal for applications requiring high - range H₂ detection (0–40,000 ppm), including industrial process control and gas storage areas.

Product Features:

1. Ultra - Wide Measurement Range
   • 0–40,000 ppm (0–100% LEL), enabling detection from low - level leaks to high - concentration environments.
2. High Sensitivity & Resolution
   • Sensitivity: 0.007 ± 0.002 μA/ppm; resolution: 80 ppm, ensuring precise H₂ concentration monitoring.
3. Rapid Response
   • Response time (T90): ≤60 seconds, allowing immediate alerts for sudden H₂ leaks.
4. Stable Performance
   • Baseline drift: Equivalent to 0–20 ppm; long - term output drift: <2% signal/month, ensuring consistent reliability.
5. Robust Environmental Adaptability
   • Operating temperature: -20°C–50°C; humidity: 15%–90% rh (non - condensing); pressure: 90–110 kPa.
6. Three - Electrode Design
   • Enhances anti - interference capability and measurement accuracy in complex gas environments.
7. Long Service Life
   • Expected lifespan: 2 years in clean air; storage life: 6 months (original packaging), reducing replacement costs.
8. Compact & Versatile
   • 4 - series size (≈5g), compatible with both portable and fixed - mounted detection equipment.

Key Technical Advantages:

• Low Cross - Sensitivity
  • Minimal interference from gases like H₂S, SO₂, and Cl₂ (refer to cross - sensitivity data for details).
• Zero Bias Voltage
  • Requires 0 mV bias voltage, simplifying circuit design for sensor integration.
• Intrinsic Safety
  • Safe for use in hazardous areas with explosive gas mixtures (consult safety certifications for compliance).
