【 摘 要 】

A fluidic calibration device of PM2.5 mass concentration monitor was developed successfully, its components were introduced and its properties were evaluated. The result showed that the designed concentration was highly consistent with the actual dust concentration, and the repeatability of the calibration device was less than 5%, and the uniformity of the calibration device was less than 7%, it indicated that the calibration device had a huge advantage in calibrating the PM2.5 monitor at low concentration of (25-75) μg/m3.
