CO/NO/NO2/Visibility Monitor

Continuous emission monitoring (CEM) is essential for maintaining air quality and adhering to environmental regulations. For over 45 years, Acoem DynOptic has been at the forefront of designing and manufacturing high-technology instruments for monitoring opacity, dust, particulate and smoke emissions. Their dedication to innovation and excellence makes them a trusted name in environmental monitoring.

The Viconox tunnel monitor is a single sensor solution for measuring nitrogen dioxide (NO₂), nitrogen oxide (NO), nitrogen oxides (NO_x), carbon monoxide (CO), visibility and temperature within a traffic tunnel, rail tunnel or other confined space.

The Viconox uses a combination of differential optical absorption and infrared spectroscopy to measure NO₂, NO and CO in tunnel atmospheres whilst measuring visibility by using the standard light transmission obscuration technique. NO_x levels are calculated from the measured NO and NO₂ concentrations.

The Viconox also measures temperature and humidity so all measurements are compensated for both factors to ensure stable readings across all conditions.

The Viconox can measure up to six (6) parameters simultaneously (including temperature) or combinations thereof. This not only minimizes capital cost but also the requirements for cabling, installation and start-up.
