Oxygen and Toxic Gas Detection

  • Can detect 400 gases, ppb to ppm
  • Lowest cost of ownership - 2-3 times the lifespan of all other brands of sensors, least amount of drift, lowest detection limits, low calibration requirements, lowest cross-interference
  • Broadest temperature range -40 to 149 F
  • Sensor diagnostics accurately predicts sensor end of life
  • Support all communication protocols (hart, fieldbus, bacnet, etc.)

Application Note: Monitoring for Oxygen Deficiency from Helium Leaks
