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. Option: H2S / TRS monitoring.

 

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.

FEATURES AND BENEFITS

  • Superior metrological performances for SO2 measurements in ranges 0-10 ppm or 0-1 ppm
  • Innovative design 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
  • Smart, connected instrument with embedded web server for the easiest, full remote control and operation of the analyzer from any PC, tablet or smartphone (configuration, calibration, test, diagnostic parameters…)
  • Integrated web-server with full remote emulation of the analyzer through the ENVEA Connect free app

 

MAIN OPTIONS:

  • Analyzer without screen for reduced environmental impact
