Face Mask Particulate Filtration Efficiency Tester is designed o test the filtering efficiency of particulate protective masks and medical masks and to determine the resistance of ordinary fabrics and medical protective masks to the constant flow of airflow.

Features/Advantages
  • Using a cold aerosol generator to produce continuous and stable aerosol particles, convenient for filling the solution.
  • Measurement of aerosol concentration using a high-precision PM2.5 sensor.
  • Anti-leakage design of whole particles to protect the safety of laboratory personnel.
  • 2 sets of Aerosol generator：Salty aerosol generator and oily aerosol generator.
  • Equipped with aerosol particle neutralization device.
  • The pneumatic clamp is equipped with a protection device, which is safe and convenient to use.
  • Configure temperature and humidity sensor, real-time display of ambient temperature and humidity（Temperature and humidity requirements：25℃±5℃，30%RH±10%RH）。
  • Equipped with glass rotor flowmeter, vacuum pump, laser dust particle counter.
  • Control system: The computer controls the test process, automatically collects data, and configures a special computer and test software.
  • The computer automatically tests the gas concentration and calculates the filtration efficiency. It can save, output, query and print the test data.
