Abstract The recently public and scientific study is going on health effects related to particulate matter (PM). Thus ambient air quality standards are being discussed worldwide A new optical particle sensor(PM-101P, HCT Co., Ltd.) has been developed that measures aerosol mass concentration(TSP, PM10, PM2.5, PM1.0) in real time. It is instrument that measures the particle size and mass concentration range of 0.3 micro-meter to 25 micro-meter and 0.01 to 20 mg per cubic meter. This instrument measures simultaneous optical sizing of single particles count and PM data. The optical particle sizing is dividing with 15 channels. The electrical pulse heights generated by light scattering from particles larger than 0.3 micron are calibrated to the diameter of PSL particles. And the PM data is based on optical particle sizing and counts. To test the performance of the PM-101P, we carried out a series of experiments to compare PM-101P with a TEOM (Series 1400a, Thermo Scientific), beta-ray (EBAM, MetOne) and APS (TSI Model 3321) for ambient aerosols. The PM mass concentration correlations between the TEOM, APS and PM-101P shows are good agreements approximately within 10%. Also we measured the particle mass concentration using the PM-101P and APS. The agreement between these two instruments is also good for these two mass fractions.
