EC4-20-NO2 Datasheet | SGX

EC4-20-NO2 Nitrogen Dioxide Electrochemical Sensor PERFORMANCE Range ................................................................... 0 - 20 ppm Maximum overload................................................... 250 ppm Sensitivity (see note)......................... 450 - 750 n A/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................15 - 90% RH (non-condensing) Pressure range .................................. 90 - 110 k Pa (nominal) Operating circuit............... see Electrochemical Toxic Sensor Application Note Applied potential ..............................................................0 V Storage life........... 6 months in original packaging (0 - 25 °C) PHYSICAL CHARACTERISTICS Label colour ...................................................................silver Weight.................................................................. 5 g approx. Dimensions ...........................................................see outline This device is designed to be Ro HS pliant. CROSS-SENSITIVITY DATA Carbon Monoxide Hydrogen Sulfide Sulfur Dioxide Nitric Oxide Chlorine Concentration (ppm) 300 15 5 35 1 Sensor Response (As ppm NO2) 0 -1.2 -5 0 -1 Important Note Do not solder to the connector pins as this may damage the sensor and thereby invalidate the warranty.
