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.
