Rated 0 out of 5
(be the first to review)

Mask Particle Filtration Efficiency (PFE) Tester is used to test the particle filtration efficiency (oil or non-oil particle) of face masks, mask raw fabric (meltblown non-woven), results in percentage level, such N95 means 95% filtration level.


  1. Product introduction

Mask Particle Filtration Efficiency (PFE) Tester can be used to detect the filtration efficiency and resistance of particles such as masks and filter materials in medical device inspection center, safety protection inspection center, drug inspection center, disease prevention and control center, textile inspection center, hospital, mask research & development and manufacturer.


  1. Technical features:
  • Color high-definition LCD touch screen is adopted, which makes the content more intuitive and the operation more convenient.
  • It is equipped with a special salt aerosol generator, which can generate aerosols of specific particle size and concentration.
  • Equipped with a series of special clamps, suitable for the detection of various masks.
  • Built-in high life photometer module, accumulated sampling time, prompt optical path cleaning.
  • Automatic control of aerosol generationand automatic calculation of capture efficiency and mask airflow resistance, reducing human intervention.
  • Built in high-precision electronic flowmeter and high-performance sampling pump to ensure flow stability.
  • Built-in compressor with automatic pneumatic clamping function.
  • Equipped with anti-static device.
  • Automatic infrared anti-pinch protection function to protect personnel safety.
  • No leakage of aerosol, and a high degree of personal protection.
  • The detection data can be exported via U disk or printed by Bluetooth printer.
  • Optional oily aerosol generator.
