4CH2O-100 Electrochemical Three - Electrode Gas Sensor For Indoor Air Quality Monitoring Devices

1. Applications (Product Uses):

• Suitable for indoor air quality monitoring devices (e.g., household formaldehyde detectors, commercial indoor air monitors) to real-time detect formaldehyde concentration and prevent health risks from excessive CH₂O.
• Applied in industrial workplace safety systems (e.g., furniture manufacturing workshops, paint spraying workshops) to monitor formaldehyde emissions during production and ensure compliance with occupational health standards.
• Used in HVAC (Heating, Ventilation, and Air Conditioning) systems with air purification functions, enabling the system to adjust filtration intensity based on real-time formaldehyde data and optimize indoor air environment.
• Integrated into environmental testing equipment (e.g., portable air quality analyzers) for on-site detection of formaldehyde in newly decorated rooms, public places (hospitals, schools), or polluted areas.

2. Features (Product Characteristics):

• High measurement accuracy: Adopts electrochemical three-electrode principle, with repeatability <±2% signal and linear output, ensuring reliable and precise formaldehyde concentration data.
• Fast response & high resolution: Response time (T90) ≤60s for quick capture of concentration changes; 0.5ppm resolution allows detection of trace formaldehyde, meeting strict monitoring requirements.
• Stable long-term performance: Long-term stability <2% signal value/month, reducing frequent calibration frequency and lowering maintenance costs for equipment.
• Wide environmental adaptability: Operates in -20°C~50°C temperature range and 15%~90% RH (non-condensing) humidity range, suitable for most indoor and industrial on-site environments.
• Low cross-sensitivity: Negligible response to non-target gases (e.g., methane, carbon dioxide) and low interference from gases like carbon monoxide, ensuring accurate measurement of formaldehyde without false alarms.
