706 Low Level NOx

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
