^{Product description}

^{SC-FT-1806D Automatic Filter(Mask) Tester (Photometer) is designed to test the initial filtration efficiency, minimum filtration efficiency and airflow resistance of filter materials and respirator (mask). This instrument can comply with NIOSH 42 CFR 84, EN 149 and South Korean standards for health masks.}

^{For filtration efficiency test, this machine can do single-machine for dual-aerosol (both oily and salty particles). Customers can choose double generator or single generator according to their own needs. Additional clean air source system is required if you choose the double-generator.}

^{This instrument has the following characteristics:}

^{1.We can offered diffierent language interface according to the customers' requirement.}

^{2.Short testing time, a single test can be finished in 1 minute.}

^{3.Controlled by microcomputer and operated by touch screen.}

^{4.Data can be stored.}

^{5.Installed ribbon printer, test results can be printed directly, and saved for a long time.}

^{6.This tester can be connected to a computer by choosing the data acquisition software.}

^{7.Stable performance, good data reproducibility.}

^{8.Maintenance-free, suitable for production companies in long-term continuous use of quality control.}
