Overview
The purpose of the oral bacterial filtration efficiency tester is to quickly, accurately, and stably detect the bacterial filtration efficiency of medical oral and oral materials. The design system based on negative pressure biosafety cabinet working environment is adopted, which is safe and convenient to use, and the quality is controllable. The method of simultaneous comparison sampling with dual gas paths has high detection efficiency and sampling accuracy. The large screen can touch the color industrial resistive screen and can be easily controlled even with gloves on. Very suitable for performance testing of bacterial filtration efficiency in metrological verification departments, research institutes, production and other related departments.
