System Introduction: 

The differential absorption spectrometer for atmospheric environment monitoring is a multifunctional device designed for the 3D detection of gaseous pollutants, specifically monitoring trace gases like SO₂ and NO₂. It provides an effective optical remote sensing method to evaluate the impact of these trace gases on air quality. The system is primarily used in urban areas and industrial sites.

Fixed-point Measurement: The system is installed at a fixed point, utilizing a rotating platform to obtain vertical and horizontal concentration profiles of SO₂ and NO₂ in the surrounding area.

Mobile Measurement: It can also be mounted on vehicles, enabling remote sensing of SO₂ and NO₂ emission fluxes along the monitoring path.

System Features:

Non-contact measurement that does not alter the properties or concentrations of the gases.

Real-time, continuous, and long-term operation with simple operation, low maintenance, and cost efficiency.

Capable of simultaneous measurement of multiple gas components, maximizing instrument utilization.

Supports offline data analysis for unattended operation.

Requires no auxiliary gases and produces no harmful emissions.

Long monitoring distance and wide range, ensuring representative data.

Versatile installation options for fixed points or vehicle-mounted monitoring.
