L’analizzatore di gas a fluorescenza UV che offre eccellenti prestazioni per il monitoraggio di SO2 con un range di 0-10 ppm o 0-1 ppm

Strumento per il monitoraggio della qualità dell’aria certificato QAL1 dal TÜV, approvato dall’US-EPA, progettato in modo ecologico. Utilizza il metodo standard per la misurazione dei biossidi di zolfo (EN 14212). Con il suo bassissimo consumo energetico e l’alimentazione a 24 V (opzione), l’AF22e è l’unico monitor SO2 sul mercato in grado di misurare senza essere collegato alla rete elettrica

  • 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
  • Continuous indoor and outdoor air quality monitoring
  • Stationary and mobile AQMS laboratories
  • Industrial fence-line monitoring
  • Continuous emissions monitoring (CEM) by dilution
  • Laboratory & field studies on SO2 / H2S / TRS effects…
  • Background (urban or suburban) Rural, Traffic, Kerbside measurement campaigns and monitoring studies
