Title:
POLLEN DISTINGUISHING METHOD AND APPARATUS, AND POLLEN SCATTERING NUMBER MEASURING METHOD AND APPARATUS
Document Type and Number:
Japanese Patent JP3558574
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a pollen distinguishing method and apparatus and a pollen scattering number measuring method and apparatus capable of heightening the accuracy of pollen forecast and automating pollen forecast in a low cost.
SOLUTION: This pollen scattering number measuring apparatus α adopts characteristic constituting means formed by a fan 1 for sucking the air and sampling suspended particles contained in the air, a first passage pipe 2 for removing coarse particles from the sampled suspended particle group, a second passage pipe 3 for removing fine particles from the particle group from which the coarse particles are removed by the first passage pipe 2 to distinguish and sample the pollen particles, and a sensor 4 for counting the pollen particles distinguished and sampled by the second passage pipe 3.
