Abstract: Objective To analyze the correlation between the counting results of Durham pollen sampler and automatic pollen monitor, discuss the advantages and defects of two instruments. Methods Durham sampler and KH3000-1 automatic pollen monitor were set up next to each other on the same altitude. Airborne pollen concentrations were measured at the same time. Results Durham sampler has the merit of low cost and can classify the granules that adhere to the sampling surface, but pollen counting using Durham sampler require much time and skilled labor; KH3000-1 automatic pollen monitor count pollen particle using laser light in real time for computer processing, without the counting using a microscope, but it is difficult to distinguish pollen species. Conclusion The onset and peak time of pollen concentration measured by two devices were consistent, the results of automatic pollen monitor affected by pollens particle size and meteorological factors.
