NH3 3E 100

Amperometric 3 electrode sensor cell

Measuring Range: 0–100 ppm
Sensitivity Range: 90 nA/ppm ± 40 nA/ppm
Zero Current at 20°C: <± 150 nA
Resolution at 20°C: <2 ppm
Bias Potential: 0 mV
Linearity: <5% full scale

Response Time at 20°C:
t50: <20 s calculated from 5 min. exposure time
t90: <120 s calculated from 5 min. exposure time

Long Term Sensitivity Drift: <10% per 6 months

Temperature Range: -40°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: > 18 months in air
