NO2 3E 50

Measuring Range: 0–50 ppm
Sensitivity Range: 200 nA/ppm ± 40 nA/ppm (negative signal)
Zero Current at 20°C: < ± 20 nA
Resolution at 20°C: < 0.1 ppm
Bias Potential: 0 mV
Linearity: < 5% full scale

Response Time at 20°C:

• t50 < 10 s calculated from 4 min. exposure time
• t90 < 30 s calculated from 4 min. exposure time

Long Term Sensitivity Drift: < 5% per month

Operation Conditions
Temperature Range: -20°C to +40°C
Humidity Range: 15–90% r.H, non–condensing

Effect of Humidity: an abrupt change of r.H. will cause a short term drift of zero
