Brief introduction: The optical attenuation method of atmospheric particulate matter of black carbon analyzer can be continuous, real-time and on-line detection of black carbon aerosol mass concentration in the atmosphere, is a special instrument monitoring of black carbon aerosol. Instrument is not only equipped with a 880 - nm standard light source, but also equipped with the other 6 kinds of reference light source (370, 450, 520, 590, 660, 950 nm), widely used in black carbon mass concentration and the optical absorption coefficient measurement, the source of black carbon aerosol distribution and the analysis of physical and chemical properties. Features: 1. The first and the only recommended standard of black carbon aerosol mass concentration measurement. 2. The system is stable and reliable, since the periodic calibration, high accuracy. 3. Double probe correction system and charge the AD system. 4. Internal high precision flow controller and related supporting design, sampling flow stability. 5. 7 band measurement, providing full of black carbon aerosol optical absorption of the information. Technical indicators: Working principle: optical attenuation method Measuring range: 50 ng/m3-100000 ng/m3 : light wavelength of 370 nm, 370 nm, 520 nm, 590 nm, 660 nm, 880 nm, 950 nm Operating environment: - 10 ℃ to 40 ℃, the general indoor environment Power: 220 v + 22 v, 50 hz + 1 hz
