7NO2-5AOF Nitrogen Dioxide Gas Sensor For Air Quality Monitoring Industrial Emission Detection

• Product Uses:
  • Air Quality Monitoring: It is mainly used for detecting the concentration of nitrogen dioxide (NO2) in the air. It is ideal for air quality monitoring applications, which can provide key data support for environmental protection departments to monitor atmospheric quality, helping to understand the pollution level of NO2 in the atmosphere.
  • Industrial Emission Detection: It can be used in industrial production processes to monitor the emission of NO2 in industrial waste gas, so as to ensure that the enterprise's waste gas discharge meets the environmental protection standards, and at the same time, it is helpful to detect the possible leakage of NO2 in the production process and protect the safety of workers.
  • Automobile Exhaust Detection: Applied to the detection of automobile exhaust, it can help monitor the content of NO2 in automobile exhaust, which is of great significance for evaluating the environmental friendliness of vehicles and promoting the improvement of vehicle emission standards.
• Product Features:
  • High Sensitivity: With a sensitivity of - 0.65 ± 0.20 μA/ppm at 20℃, it can detect trace amounts of NO2 gas, which is conducive to the early discovery of NO2 concentration changes.
  • Fast Response: The response time (T90) is ≤ 90 s, which can quickly respond to the change of NO2 concentration, and can provide real - time data for real - time monitoring systems.
  • Good Stability: The zero signal at 20℃ is < ± 0.4 μA, and the baseline shift in the temperature range of - 20℃ - 50℃ is < 0.5 ppm. The long - term output drift is < 2% signal/month, which can maintain relatively stable performance in different environmental conditions, reducing the frequency of calibration and maintenance.
  • Strong Anti - interference Ability: Equipped with a filter, it can eliminate the cross - sensitivity to SO2 and O3, which can effectively avoid the interference of other gases and improve the accuracy of NO2 detection.
  • Simple Installation: It can be used as a pin - to - pin replacement for standard 7 - series nitrogen dioxide sensors, which is convenient for equipment upgrading and maintenance. And it has no special requirements for installation orientation, with a housing made of ABS material, weighing about 8 g, which is lightweight and easy to install in various monitoring equipment.
  • Wide Applicable Temperature Range: It can work normally in the temperature range of - 20℃ - 50℃, and has a certain adaptability to different climatic conditions, which can meet the needs of different regional and environmental monitoring.
  • Intrinsic Safety: It has intrinsic safety characteristics, with a maximum current of < 0.2 mA at 20 ppm NO2, a maximum open - circuit voltage of 1.3 V, and a maximum short - circuit current of < 1.0 A, which can be used safely in some dangerous environments
