by Using Latex Spheres ASTM F2299 Medical Face Mask Penetration Tester

AT900 Automated Filter Tester is a universal tester, development according to the standard of ASTM F2299, it mainly used for
detecting the efficiency of the particulate respirator filtration and detecting the filtration efficiency and resistance of
material. Using imported optical particle counter as detector to ensure accurate results.

The latex particle spray after Ruskin nozzle and drying, then form in to aerosol. The system adopts precision instrument to
control flow and concentration, and through integrate of system to communicate with computer, the system has good stability, and
it is easy to operate.

By detecting the concentration of upstream and downstream, and then calculate the results through the formula. Airflow can be
real-time monitored through electric proportional valve and flow meter, to ensure the accuracy of the test flow and the stability.
The aerosol concentration can be monitored by electrical proportional valve and differential gauge, and provide stable test
particles.
