Brand: GESTER
Model: TSI
Lab Location: : KSS-502 room at 5th floor of Kasamsri building 
Fundamental : The particle filtration tester is designed for supporting NIOSE 4 for analysis of Particle filtration Efficiency for respirator. The compartment of the built-in system is a composted aerosol generator, Neutralizer, air mixing chamber, sample holder, and particle counter. The testing method is the aerosol particle size (NaCl) exposed to in the range between 0.3 µm by generator. After that the aerosol is dried and passed through to the test holder and detected by a light-scattering photometer.
Type of Detector : light-scattering photometer
Type of Samples :Respirator and filter
Testing method : NIOSH 42 CFR 84
