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