- Model AF22e e-Series - Sulfur dioxides Analyzer SO2



UV Fluorescence gas monitor offering excellent performances for the monitoring of SO2 in the range 0-10 ppm or 0-1 ppm. Eco-designed, reference air quality monitor, QAL1 certified by the TÜV, US-EPA approved. Utilizes the standard method for the measurement of sulfur dioxides(EN 14212). With its ultra low power consumption & 24 V supply (option), the AF22e is the sole SO2 monitor on the market able to measure without being connected to the power grid.

  • Superior metrological performances for SO2 measurements in ranges 0-10 ppm or 0-1 ppm
  • Innovative conception of the optical module for excellent sensitivity and signal stability
  • Real-time calibration graph, animated synoptic, auto-diagnostic, control and maintenance data screens can be displayed while the instrument is operating
  • Embedded Communication Protocol for XR® Software with automatic recognition and configuration
  • Able to withstand temperatures up to 45-50 °C without air conditioning
  • Special architecture means that no additional pump is necessary in case of permeation bench (in option)
  • Automatic recognition of plugged electronic boards or optional devices: plug & play principle
