NH3 3E 100 SE

Amperometric 3 electrode sensor cell

Measuring Range: 0–100 ppm
Sensitivity Range: 130 nA/ppm ± 30 nA/ppm
Zero Current at 20°C: < ± 100 nA
Resolution at 20°C: <1 ppm
Bias Potential: 0 mV
Linearity: <10% full scale

Response Time at 20°C
t50: <20 s calculated from 5 min. exposure time
t90: <60 s calculated from 5 min. exposure time

Long Term Sensitivity Drift: <5% per 6 months

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 reading

Sensor Life Expectancy: > 24 months in air
