UV/IR Doas Based Open Path Air Quality Monitoring System [System 300(Opsis)]
The Opsis System 300 is a cost-effective, high-performance, air quality monitoring package, designed for trend, street-level and fence-line applications. The measurements are based on the DOAS technique (Differential Optical Absorption Spectroscopy), allowing continuous monitoring of several compounds. System 300 is available in three configurations:
BASIC: for sulfur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3)
BTX: for Benzene, Toluene, Xylene
EXT: for SO2, NO2, O2, Benzene, Toluene, Xylene
- Approved by MCERTS, TÜV and U.S. EPA & 19 other agencies across world.
- Monitoring path length : 100 to 2000 meters or wider range.
- One IR Interroferrometer Analyser can Monitor Several IR Gases
- The System 300 is not affected by contaminated sample lines, NO2 converters, hydrocarbons, blocked filters etc., known problems which affect the data quality from point monitoring systems.
