NE7-CO-H10000 Electrochemical gas sensor For Industrial Safety

NE7-CO-H10000 Electrochemical gas sensor

Key Features:

1. Anti-Interference Design:
   • Four-electrode structure enables internal compensation for hydrogen sensitivity, eliminating interference from unburned hydrogen (H₂) in combustion processes. Suitable for complex scenarios like gas equipment and industrial exhaust monitoring.
   • Cross-sensitivity performance:
     • No response: Cl₂, CH₄, C₂H₅OH, etc.
     • Slight response: H₂ (100ppm ≈ <70ppm CO equivalent), NO (35ppm ≈ <7ppm CO equivalent), NO₂ (10ppm ≈ -0.5 to +1ppm CO equivalent).
2. Environmental Adaptability:
   • Temperature range: -20°C to +50°C with cold-start capability at -20°C.
   • Humidity impact: Stable performance in 15%–90% RH; output fluctuation ≤5ppm under sudden humidity changes.
   • Durability: Passed -20°C/50°C thermal shock test (10 cycles) with minimal performance degradation.
3. High Precision & Reliability:
   • 0.5ppm resolution and repeatability < ±2%, suitable for occupational safety (e.g., mines, chemical plants) and environmental monitoring (e.g., indoor air quality).
   • Built-in temperature compensation reduces zero drift caused by ambient temperature changes.

Application Fields:

• Industrial Safety: CO leakage monitoring in gas boilers, furnaces, power plants, etc.
• Environmental Monitoring: Indoor air quality detection, underground parking ventilation control.
• Combustion Control: Combustion efficiency optimization for gas water heaters, stoves (requires integration with O₂ sensors).
• Portable Devices: Handheld CO detectors, multi-gas composite monitors.

Physical Parameters:

• Dimensions: Industrial-standard design compatible with 主流 gas detection equipment interfaces.
• Weight: Approximately 9.9g (reference for similar electrochemical sensors).
• Interface: Standard pin-type design for plug-and-play integration.

Usage Recommendations:

1. Calibration Cycle: Perform zero and span calibration every 6 months to ensure long-term accuracy.
2. Storage Conditions: Store at -20°C to +50°C with humidity <60% RH when unused; avoid prolonged exposure to high humidity or polluted gases.
3. Lifespan Management: Typical service life is 24 months (dependent on usage environment); monitor sensitivity decay regularly.
