YYJ267 Bacterial Filtration Efficiency Tester

Short Description:

Instrument use:

It is used to detect the bacterial filtration effect of medical masks and mask materials quickly, accurately and stably. The design system based on the working environment of the negative pressure biosafety cabinet is adopted, which is safe and convenient to use and has controllable quality. The method of comparing sampling with two gas channels simultaneously has high detection efficiency and sampling accuracy. The large screen can touch the color industrial resistance screen, and can be easily controlled while wearing gloves. It is very suitable for measurement verification departments, scientific research institutes, mask production and other relevant departments to test the performance of mask bacterial filtration efficiency.
