Product Details
NE4-HCHO Electrochemical Formaldehyde Gas Sensor For Indoor Air
Quality (IAQ) Monitoring In Homes
Key Features :
- High sensitivity to formaldehyde (HCHO) with a detection range of
0-10 ppm, ensuring accurate concentration monitoring.
- Excellent repeatability (±5%) and low baseline drift (<0.2 ppm
at 0-40℃) for reliable long-term operation.
- No bias voltage required, simplifying circuit design and reducing
system complexity.
- Compact size (≈5g weight) and industry-standard form factor,
enabling easy integration into existing devices.
- Wide operating temperature (-20 to 50℃) and humidity (15-90% RH)
ranges, adapting to diverse environments.
- Low power consumption, ideal for battery-powered portable detection
equipment.
- Built-in charcoal filter to reduce cross-sensitivity from
interfering gases, enhancing measurement accuracy.
- Long expected service life (over 1 year) and no position
sensitivity, ensuring consistent performance.
Applications :
- Portable formaldehyde detectors for indoor air quality (IAQ)
monitoring in homes, offices, and schools.
- Industrial safety equipment for HCHO detection in paint factories,
furniture manufacturing, and chemical plants.
- Smart home air quality monitoring systems to alert on formaldehyde
超标 (exceedance of standards).
- HVAC (Heating, Ventilation, and Air Conditioning) systems for
real-time formaldehyde level regulation.
- Environmental monitoring devices for tracking HCHO emissions in
construction sites or renovation projects.
- Medical and laboratory equipment requiring precise formaldehyde
sensing in controlled environments.
- Consumer electronics (e.g., air purifiers, smart detectors)
integrated with HCHO detection functionality.
