YX-AQMS air quality monitoring system monitors particulate matter (PM10, PM2.5, T ..

System Overview YX-AQMS air quality monitoring system meets the People's Republic of China Environmental Protection Industry Standard GB3095-1996 "Ambient Air Quality Standard", HJ / T193-2005 "ambient air quality monitoring technical specifications." Monitoring system includes: SO2 analyzer, NOx (NO2, NO) analyzer, O3 analyzers, CO analyzers, PM10 analyzers, VOC analyzer, THC analyzer and meteorological multi-parameter monitor; dynamic calibration system includes zero gas generator and multi-gas calibrator. System and the principle of sulfur dioxide SO2 monitors (SO2) Monitor UV fluorescence method, the principle is the sulfur dioxide molecules in the excited state of the ultraviolet radiation into sulfur dioxide, when it returns to the steady state light, filtered light flux generated at this time rays are selectively receive detection. NOx (NO, NO2) monitor nitrogen oxides (NOx) by chemiluminescence monitor, use the sample gas nitric oxide and ozone reaction of nitrogen dioxide, chemiluminescence intensity produced simultaneously with nitric oxide concentration have proportional relationship, in order to continuously measure the concentration of nitrogen oxides in the atmosphere. CO monitors carbon monoxide (CO) monitors the use of non-dispersive infrared absorption method, which is based on the relationship between absorption intensity and the concentration of carbon monoxide in line with the characteristic wavelength Lambert - Beer law. O3 monitor ozone (O3) Monitor UV absorption method, ozone molecules 254nm wavelength of UV light has a characteristic absorption, and the relationship between the extent of absorption and the ozone concentration of ozone ultraviolet conform Lambert - Beer law. Particulate Monitor (PM10, PM2.5, TSP, user selectable) Particulate Monitor using β-rays (β-ray) attenuation method to measure particle concentration. The principle is to some extent by β particles weaken medium is based on the mass density of the material varies exponential function. THC monitor THC monitor the flame ionization detection method and selective combustion technology combine to make a single detector method has been greatly improved, can simultaneously CH4, NMHC, and THC were no zero drift for continuous monitoring. Multiple Gas Calibrator Multi Calibrator gas dilution system and a variety of gases having standard gas source, dynamically configure a variety of different concentrations of the standard gas source, to achieve a variety of gaseous analyzer single-point or multi-point calibration function; receiving control instructions automatic zero / span (single or multi-point) calibration can be manually calibrated. Zero Air Generator zero air generator is provided for the Multi zero air gas calibrator design, the system includes a rack-mounted compressed air source and a series of optional eliminate device can produce both clean and dry dilution is required The "zero air."
