Mask particle filtration efficiency tester

Product Description

Mask particulate filtering efficiency tester is a detection device for detecting the filtering performance, protective filtering efficiency, and filtering effect of protective masks. Currently, masks are mainly divided into air filtering masks and air supply masks. This testing instrument is suitable for medical device 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 production enterprises. Comply with GB 2626-2006 Respiratory protective equipment-Self-priming filter anti-particulate respirator, GB 19083-2010 Medical protective mask technical requirements, GB / T 32610-2016 Daily protective mask technical specifications.

Equipment composition and equipment principle:
It consists of oil mist generator, data acquisition software, tooling device for testing products, concentration detector, concentration detector after filtering, computer data calculation device, pressure adjustment device and tooling pipeline test auxiliary device.
The concentration of the mask before and after filtering is detected by the photometer in the system to complete the detection of the protection efficiency of the particulate matter of the mask.
