EC4-20-NO2

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 Resolution.........................................................0.1 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 humidity........
