PS-2 Pollen Sensor

Comapct, Light and Low Cost

Optical unit and circuit are fully covered with plastic case, and built-in heater keeps the sensor away from dew.

Built-in Heater prevents dew

Fan enables constant and larger sampling of air. Pollen count information can be made available without delay by taking advantage of the real time analysis.

Built-in Suction Fan

This sensor detects the particle with light scattering method, using one light emitter and two light receptors, and discriminates pollen from other particles with two factors "scattered light intensity" and "degree of polarization". Patented.
