Brief introduction
Atmospheric particulate black carbon analyzer using optical attenuation method of mass concentration of continuous, real-time and on-line measurement of black carbon aerosol in atmosphere, is a special instrument for monitoring of soot aerosol. The instrument is not only equipped with 880 nm standard light source, is also equipped with the other 6 reference light source (370, 450, 520, 590, 660, 950 nm), analysis of source distribution and physicochemical characteristics of black carbon aerosol measurement, is widely used in the black carbon mass concentration and optical absorption coefficient. Features
With "QX/T 68-2007 method observation of black carbon aerosol optical attenuation method" standard, is the first and only recommended method of black carbon aerosol mass concentration measurement.
The system is stable, reliable, periodic self calibration, and high accuracy.
The dual detector system improves the accuracy of the detection data and the anti-interference ability. The charge integrating AD system improves the detection accuracy of the multi-channel micro current signal.
Internal high precision flow controller and related supporting design, sampling flow stability.
7 band optical measurement, provide black carbon aerosol absorption comprehensive information, and help to remove the effects of distractors, especially suitable for the application of scientific research. Technical parameter
