ASTM F2101 bacterial Filtration Efficiency (BFE)Tester
Medical face mask Bacterial filtration efficiency Tester can quickly and accurately measure the filtration efficiency of filtration protection equipment and materials . Salt aerosols or oily aerosols can be used as the test carriers, which are in line with the requirements of US Occupational Safety and Health Council NIOSH standards.
Mask filter performance tester utilizes advanced technology and microprocessor for controlling. The tester is designed with a good user interface and setting mode, which can simplify the training and operation. The test results directly display, easy and quickly.
Application
Suitable for professional filtration testing
The instrument is mainly used for the performance testing of respiratory protection products, disposable masks, filter medium, the security testing which is suitable for such products, basic filtering performance evaluation and guidance for the development of new products.
Mask filter performance tester is easy to operate. Using oily aerosol and solid photometric detection technology, it can automatically measure the filtration efficiency and pressure drop of filter materials, filter masks and filter elements in a wide range of volume flow.
