EC4-20-NO2 Nitrogen Dioxide Electrochemical Sensor PERFORMANCE Range 0 - 20 ppm Maximum overload 250 ppm Sensitivity (see note) 450 - 750 nA/ppm NO2 Zero in air at 20 °C<0.9 ppm NO2 Resolution0.1 ppm NO2 Linearity linear across range Response time, t90 <35 s Long-term output drift<2% signal/month Warranty 2 years Note: This output current is negative.
This is because the sensor reaction is a reduction of the target gas.
OPERATING CONDITIONS Temperature range -20 to +50 °C Operating humidit
