| Abstract: | It is important to test the concentration of test aerosol accurately for HEPA/ULPA filter efficiency testing. This paper presents the principles and characteristics of three particle detectors(photometer, optical particle counter and condensation nucleus counter ),then, their existing problems in practice were analyzed in detail. Based on the discussion,it was concluded that optical particle counter and condensation nucleus counter will be the major particle detectors for HEPA/ULPA filter testing in the future. |
