NE4-HCHO-S Electrochemical Three-electrode System Industrial-grade Formaldehyde Sensor
I. Product Applications:
- Indoor Air Quality Monitoring:
- Used for formaldehyde concentration detection in homes, offices, hotels, etc., to ensure indoor environmental safety.
- Compatible with air purifiers and fresh air systems to achieve real-time feedback and automatic adjustment of formaldehyde concentration.
- Industrial Process Control:
- Monitoring formaldehyde gas leakage in chemical production to prevent safety accidents.
- Detection of formaldehyde emission in building materials, coatings, and other industries (e.g., environmental performance testing of boards and furniture).
- Environmental Protection & Scientific Research:
- Formaldehyde pollution early warning in environmental monitoring stations.
- Data collection for formaldehyde-related experiments in universities and research institutions.
- Medical & Health Scenarios:
- Safety monitoring of formaldehyde-sensitive environments such as hospital wards and laboratories.
- Effect evaluation in formaldehyde treatment services (e.g., concentration detection after formaldehyde removal construction).
II. Product Features:
- High Sensitivity & Accuracy:
- Sensitivity reaches 500±150nA/PPM, capable of detecting formaldehyde concentrations as low as 0.01PPM to meet indoor environmental safety standards.
- Zero drift <0.2PPM, repeatability ≤±5%, ensuring strong long-term stability.
- Advantages of Electrochemical Principle:
- Three-electrode design (working electrode, counter electrode, reference electrode) with strong anti-interference ability, reducing cross-effects from other gases (e.g., ethanol, benzene).
- No heating element required, low power consumption, suitable for battery-powered devices (e.g., portable detectors).
- Wide Operating Range & Environmental Adaptability:
- Stable operation at -20℃~50℃ and 15%~90%RH humidity, adapting to different climatic conditions.
- Tolerant to atmospheric pressure fluctuations (0.9~1.1atm), suitable for areas at different altitudes.
- Easy Integration & Low Cost:
- 0mV bias voltage, recommended 10Ω load resistance, simple circuit design compatible with various MCUs (e.g., Arduino, STM32).
- Industrial-grade packaging with high cost-effectiveness, suitable for mass application in consumer electronics and monitoring equipment.
- Rapid Response & Reliability:
- Response time ≤120s, providing real-time feedback on formaldehyde concentration changes to meet emergency monitoring needs.
- Maximum overload 50PPM, recoverable after short-term high-concentration exposure, extending service life.
