Brief introduction: LGH - 01 long optical path air quality automatic monitoring system is mainly used for continuously monitoring city, highway, airport, cement, chemical fertilizer plants, sulfuric acid plant, wood processing plants, calcining plant air quality condition. Gaseous pollutants measurement with the national environmental protection approval and the U.S. environmental protection agency (USEPA) recommended method, using the Optical difference Absorption spectrometry (DOAS, Differential Optical Absorption Spectroscopy) was developed. The device is through the analysis of the absorption spectra of pollution gases to the atmosphere to the inversion of pollutants concentration, a traditional point system incomparable technical advantage. Features: 1. A long optical path DOAS gas monitor is a collection of optical remote sensing technology, spectroscopy, electronic technology and computer technology in the integration of high-tech products. The product has its own characteristics compared with the traditional point of equipment: 2. Use wire measurement, monitoring coverage area is large (a few hundred meters optical path), can produce different direction or the monitoring results, the accuracy of the measurement result and representation has the incomparable technical advantage point instrument, more be helpful for the characterization and evaluation of environmental air quality; 3. The measurement process without sampling, a analyzer can monitor various gases, such as SO2, NO2 and O3 and BTX up to more than 30 kinds of parameters; 4. USES the array detector, spectrum, relative to other companies adopt mechanical scanning spectrum analysis method, instrument inside have no moving parts, 5. Monitoring period is short, high measurement precision, instrument more stable and long service life; 6. With functions of automatic wavelength calibration and sample gas calibration; 7. The light signal transmitting and receiving in the same side, the other end do not need to install the active components, convenient installation, use and maintenance; 8. Low operating cost, less material consumption, convenient maintenance
