Product Description:
YJJ ME3-CH2O Electrochemical Formaldehyde CH2O Sensor Civil Industrial Fields
Features:
I. Core Parameters (Official Standards) Table
Parameter item Specification Explanation
Detected gas Formaldehyde (CH₂O / HCHO) One type of carcinogen, the main pollution source in indoor decoration
Detection principle Tri-electrode electrochemistry When gas is oxidized, an electric current is generated, and the concentration is proportional to the current
Measurement range 0 - 10 ppm Covers the national standard indoor safety limit (0.10 ppm)
Overload capacity 100 ppm Does not damage in short-term overload
Sensitivity (11.8 ± 6) μA/ppm Approximately 11.8 microamps of current is generated per ppm of formaldehyde
Resolution 0.1 ppm Accurately detects minute changes in formaldehyde concentration
Response time (T90) ≤ 90 seconds The response speed reaches 90% of the concentration
Operating temperature -20℃ ~ +40℃ Suitable for indoor / industrial conventional environments
Operating humidity 15 - 90% RH (no condensation) Resistant to humidity, suitable for most scenarios
Service life 2 years in air General service life of electrochemical sensors
Size φ20 × 16.6 mm Standard 4-series industrial size, easy to replace
Bias voltage 300 mV Requires an external power supply to provide bias voltage
Load resistance 10 Ω Recommended external resistance value
II. Main applications
Core positioning: Precise monitoring and safety alarm of formaldehyde concentration in indoor / industrial environments
Civilian / Household (most extensive)
Household formaldehyde detector: Self-testing of formaldehyde in new houses, new cars, and furniture
Air purifier / new air conditioner: Linked control, automatic purification when concentration exceeds the limit
Smart home: Indoor air quality (IAQ) monitoring system
Industrial / commercial safety
Textile / furniture / sheet metal factory: Monitoring of volatile gases in production workshops
