DRK506 Particle Filtration Efficiency Detector(PFE)-ASTMF2299

【Introduction】

Medical surgical mask particle filtration efficiency PFE tester is suitable for medical instrument inspection center, safety protection inspection center, labor protection inspection center, drug inspection center, disease prevention and control center, textile inspection center, hospital, mask and respirator manufacturers, etc.

【Features 】

The PFE tester for particle filtration efficiency of surgical masks is equipped with a special salt aerosol generator, which can produce aerosols with specific particle size and concentration.

Equipped with a series of special fixture, suitable for the detection of all kinds of masks.

Built-in high life photometer module, sampling time accumulation, prompt light cleaning.

Automatic control of aerosol generation, automatic calculation of capture efficiency and mask airflow resistance, reduce human intervention.

PC control with Drick software, easy to operate and save the test report!

Built-in high precision electronic flowmeter and high performance sampling pump to ensure flow stability.
