AF22e Sulphur Dioxide Analyser

Preferred Communication Method
This field is for validation purposes and should be left unchanged.


The AF22e is a continuous ambient air-quality monitoring analyser (CAMs), based on the ultraviolet fluorescence principle, which is the standard method for the measurement of SO2 concentration (EN 14212).

Specific Features:

  • Superior metrological performances for SO2 measurements in the range 0-20 ppm
  • Innovative conception of the optical module for excellent sensitivity and signal stability
  • Simultaneous multi-screen remote access via Wifi or Lan using the dedicated application ESA ConnectTM for control, diagnostics, software update
  • Real-time calibration graph, animated synoptic, auto-diagnostic, control and maintenance data screens can be displayed while the instrument is operating
  • Service assistant inside: detects early signs of trouble, allows predictive maintenance, identifies the service needed and guides the service operations step by step: increased productivity on site, reduced downtime, more efficiency, less training
  • Includes embedded Communication Protocol for XR® Management
  • Software with automatic recognition and configuration
  • Ultra low power consumption (43 W) means environment-friendly and cost-saving analyser
  • Breakthrough mechanical design for weight and power saving as well as thermal insulation & reliability
  • Special architecture means that no additional pump is necessary in case of permeation bench option
  • Automatic recognition of plugged electronic boards or optional devices: plug and play principle
  • SmartStatusLightTM power button on the front panel indicating if the instrument is ready to use or not (ON/OFF, Alarm, Maintenance required


  • Ambient air quality monitoring
  • Indoor air quality continuous monitoring
  • Mobile and fixe monitoring stations
  • Traffic stations: near-road, tunnels, canyon streets
  • Medical gases measurements
  • NO - NO2 measurement according to the European Directive 2008/50/CE
