mask automatic filter performance tester uses the most advanced technology and design concepts, to meet a variety of test standards and the latest National standard GB / T 32610.Only relatively little operation is required to complete all the function and operation. Hardware performance of mask automatic filter performance tester is stable and excellent in repeatability. Software design meet with people's thinking mode, the interface is user-friendly, and the functional and parameter settings are very reasonable. It is convenient to user for academic research and product development.

Application:

Mask Automatic Filter Performance Tester is used for testing professional filter material and filtration efficiencyof a wide range of air filters including HEPA and ULPA filter, respirator, filter cartridge and protective clothing test. It also can use salt or oil mist to test filter media. Rapid acquisition of filter media performance evaluation parameters, and accurate evaluation of filter material quality, performance, life and so on. It is convenient to user for academic research and product development of new filter materials, product quality control, material performance verification.

Used to test the filtration efficiency of particulate matters such as masks and filter materials.
