| | | Low Level NOx Data Sheet (P/N 706) | | |
| | | |
| | | |
| | | SENSOR FEATURES: • Sensor detects very low NOx concentrations (<0.5 ppm to 10 ppm) • Larger dynamic range available (5 ppm to 100 ppm, may require larger power input to heater) • Environmental temperature range of — 20 to 50°C • Environmental humidity range of 0 to 90% RH, non-condensing • Low dependence on flow rate | | |
