Medical surgical mask particle protection effect tester

The mask particle protection effect detector is placed in the volume of 500L self-cleaning detection chamber with national standard head model, the mask to be tested is worn on the head model, salt aerosol with a median mass diameter of 0.6μm and a concentration of 25mg/m3 and oil aerosol with a median mass diameter of 0.3μm and a concentration of 25mg/m3 are input into the self-cleaning detection chamber, and the head model makes a sine curve to simulate Breathing, using upstream and downstream photometer sampling to detect the concentration of salt aerosol and oil aerosol before and after the mask, and calculate the filtering efficiency of the mask particulate matter.


Technical features:

Mask particle filtration efficiency detection and breathing resistance detection integrated design, a machine multi-purpose.
Self-cleaning test chamber configuration operating gloves, convenient for the replacement of masks to be tested.
Three types of head mold compatibility design, head mold plug and play, easy to replace.
External salt and oil aerosol generator can be controlled to control the concentration of particulate matter occurrence.
Large touch display design, automatic display of respiratory flow curve and automatic calculation of particulate matter filtration efficiency.
Full range of particulate matter leak-proof design to protect the safety of experimenters.
Photometer long life laser light source, high precision photomultiplier tube detection.
Photometer working time statistics, automatic prompting cleaning time.
High efficiency filter use time statistics automatically, prompting the replacement of high efficiency filter.
Historical data can be exported via U disk or printed via embedded printer.
