US-EPA Particulate Monitor & Particulate samplers

Ambient Air gas analyzer for CO, CO2, NO, NO2, NOx, SO2, H2S, TRS, HC(Methane CH4& non Methane), O3, VOC, NH3, BTEX. Particulate monitor and particulate sampler (PM1, PM2.5, PM10, TSP)

US-EPA Approved Gases, Particulate Monitor & Particulate samplers

Approved gas monitors for the continuous measurement of criteria pollutants and specific gas parameters concentrations in ambient air to provide reference measurement for the implementation of clean air national and international regulations as well as gas purity, quality control and industrial hazardous leakage monitoring.


  • Continuous indoor and outdoor air quality monitoring
  • Stationary and mobile AQMS laboratories
  • Leakage detection in industrial applications
  • Continuous emissions monitoring (CEM) by dilution
  • Background, rural, urban or sub-urban, industrial, traffic, roadside studies
  • Laboratory and field studies on pollution effects


All the analyzers have been fully eco-designed, with a special consideration to the environmental impacts of the product during its whole life-cycle.

The exclusive «inside the box» recyclable foam modular concept makes the product more robust, power saving, simpler to service and eco-friendly.


  • Environmental friendly: Low carbon footprint / Over 95% of the analyzer can be recycled / Ultra low power consumption / Common electronic boards: optimized spare parts stock
  • SmartStatusLight™ power button for status of operation (ON/OFF, Alarm, Maintenance required…)
  • Economic, Easy and reduced maintenance
  • Service Assistant inside
  • Interactivity: Smart, connected instruments.
