e-Series Nitrogen Oxides Analyzer NO, NOx & NO₂

AC32e

Precise PM1, PM2.5, PM4.25, PM10 and TSP monitoring in indoor ambient air.

Eco-designed, reference air quality monitor, based on the chemiluminescence technology, the standard method for the measurement of nitrogen oxides (EN 14211). QAL1 certified by the TÜV, US-EPA approved. With its ultra low power consumption & 24 V supply (option), the AC32e is the sole NOx analyzer on the market able to measure without being connected to the power grid.

Multi-screen remote access via Wifi or Ethernet using the ENVEA Connect™ application for control, diagnostics, software upgrade

  • Excellent sensitivity & metrological performances for NO, NO2 and NOx measurements in the range 0-1 ppm and optionally NH3
  • Real-time calibration graph, animated synoptic, auto-diagnostic, control and maintenance data screens can be displayed while the instrument is operating
  • Service assistance inside: detects early signs of trouble, allows predictive maintenance, identifies the needed service and guides service operations step by step: increased productivity on site, reduced downtime, more efficiency, less training…
  • Embedded Communication Protocol for XR® Software with automatic recognition & configuration
  • Able to withstand temperatures up to 45-50 °C without air conditioning
  • 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…)
  • Continuous indoor and outdoor air quality monitoring
  • Stationary and mobile AQMS laboratories
  • Ammonia impact assessments from intensive farming & livestock installations
  • Industrial fence-line monitoring
  • Continuous emissions monitoring (CEM) by dilution
  • Background (urban or suburban), Rural, Traffic, Kerbside measurement campaigns and monitoring studies
  • Laboratory and field studies on pollution effects
