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.
