AS32M- ANALYZER FOR QUICK AND DIRECT (WITHOUT CONVERSION) NO2 MONITORING

AS32M- ANALYZER FOR QUICK AND DIRECT (WITHOUT CONVERSION) NO2 MONITORING

Designed to alleviate potential disadvantages of the chemiluminiscence method and to provide the most accurate value for NO2 concentration measurements.

  • Direct and continuous monitoring of Nitrogen Dioxides
  • Provides fast and accurate NO2 measurements
  • Extremely compact, easy to use with minimal maintenance (periodic change of particle filter)
  • Completely autonomous, automatic and capable of detecting short events with high precision
  • Direct measurement of the sample - no chemical conversion required
  • Innovative technology plus touchscreen convenience (optionally)
  • US EPA Automated Equivalent Method
