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.
