(be the first to review)

Mask particulate filter efficiency and air flow resistance tester can be used for medical equipment inspection center, safety protection inspection center, drug inspection center, disease prevention and control center, textile inspection center, hospital, mask research and development and manufacturers, etc. It can conduct the tests of standards like GB/T 32610-2016,TAJ 1001-2015,YY 0469-2011, etc.




TN148 Mask particulate filter efficiency and air flow resistance tester is used to test the filtration efficiency of daily protective masks, medical masks, and respirators for particulate matter.

TN148 Mask particulate filter efficiency and air flow resistance tester is equipped with a special salt aerosol generator, generating aerosol with specific particle size and concentration. It is suitable for leak detection of masks, filter materials, and high-efficiency filters for medical device inspection centers, disease prevention and control centers, hospitals, and high-efficiency filter manufacturers.


● With a color high-definition LCD touch screen, the content is more intuitive and the operation is easier.
● Equipped with special salt aerosol generator, can generate aerosol with specific particle size and concentration.
● Equipped with multiple series of special fixtures, suitable for the detection of various masks.
● Built-in high-life photometer module, accumulated sampling time, prompting cleaning of optical path.
● Automatically control the occurrence of aerosol, automatically calculate the collection efficiency and the airflow resistance of the mask, and reduce 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.
● Comes with anti-static device.
● Automatic infrared anti-pinch protection function to protect personnel safety.
● There is no leakage of aerosols and a high degree of personal protection.
● The detection data can be exported by U disk or printed by Bluetooth printer.
● Optional oily aerosol generator.
