1 PC ME4-NO2 Nitrogen Dioxide Gas Sensor

ME4-NO2 nitrogen dioxide gas sensor is constant potential electrolysis type. Oxidation-reduction reaction with nitrogen dioxide and oxygen take place respectively on the working electrode and on the counter electrode. The process releases electric charge and generates current. The current is in direct proportion to the concentration of nitrogen dioxide. So the concentration of the target gas could be got by measuring the value of current. Application It is used for nitrogen dioxide detection in industrial occasions, mine and environmental protection field. Features Low power consumption High precision High sensitivity Wide linear range Good anti-interference ability Excellent repeatability and stability Specifications Detection gas Nitrogen dioxide (NO2) Detection range 0～20ppm Max range 150ppm Sensitivity (1.2±0.3) µA/ppm Resolution 0.1ppm Response time (T90) ＜30S Bias voltage 10Ω (recommended) Load resistance 0mV Repeatability ＜2% Output value Stability (/month) ＜2% Output linearity Linear Zero drift (-20℃～40℃) 0.2ppm Temperature range -20℃～50℃ Humidity range 15%～90% RH Pressure range standard atmospheric pressure±10% Life span 2 years (in air)   * The description and specifications might be changed without notice.
