Product catalog summary

Performance Specifications:

Sensitivity: -600 to -1100 nA/ppm in 10ppm NO2.
Response Time: t90 < 60 seconds from zero to 10ppm NO2 with a 33Ω load resistor.
Zero Current: < ± 0.2 ppm equivalent in zero air.
Resolution: RMS noise < 0.02 ppm equivalent with a 33Ω load resistor.
Range: Performance warranty limit at 20 ppm NO2.
Linearity: Error < ± 0.3 ppm at full scale, linear at zero and 10ppm NO2.
Overgas Range: Maximum stable response to gas pulse at 100 ppm.

Lifetime Specifications:

Zero Drift: < 0.1 ppm equivalent change/year in lab air.
Sensitivity Drift: < 2% change/month in lab air, tested monthly.
Operating Life: > 24 months until 80% of original signal (24-month warranty).

Environmental Specifications:

Sensitivity at -20°C: 101% to 109% (output at -20°C/output at 20°C) at 5ppm NO2.
Sensitivity at 50°C: 78% to 93% (output at 40°C/output at 20°C) at 5ppm NO2.
Zero at -20°C: < ± 0.15 ppm equivalent change from 20°C.

CO: < 0.1% at 400ppm.
C₂H₄: < 0.1% at 400ppm.
NH₃: < 0.1% at 20ppm.
CO₂: 0% at 5% (Vol).

Key Specifications:

Temperature Range: -30 to 50°C.
Pressure Range: 80 to 120 kPa.
Humidity Range: 15 to 90% rh continuous.
Storage Period: 6 months at 3 to 20°C in a sealed pot.
Load Resistor: 33Ω for optimum performance.

Additional Notes:

All sensors are tested at ambient conditions with a 10 ohm load resistor unless otherwise stated.
Customers should test sensors under their own conditions to ensure suitability.
Exposure above 85% rh and 40°C is warranted for a maximum of 10 days.
