El analizador de gases basado en CLD ofrece un rendimiento superior para medir NO, NO2 y NOx con un rango de 0-1 ppm o 0-10 ppm. Monitoreo opcional de NH3

Instrumento de monitoreo de la calidad del aire certificado y diseñado ambientalmente, basado en tecnología de quimioluminiscencia, el método estándar para medir los óxidos de nitrógeno (EN 14211). Certificado QAL1 por TÜV, aprobado por US-EPA. Con su bajísimo consumo energético y su alimentación de 24 V (opcional), el AC32e es el único analizador de NOx del mercado capaz de medir sin estar conectado a la red eléctrica.

Acceso remoto multipantalla a través de Wifi o Lan utilizando la aplicación ENVEA Connect™ para control, diagnóstico y actualización de software.

  • 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
