Description
The PMFT 1000 M tests respirators better than the standard with additional accurate analysis of filter mask efficiency for SARS-CoV-2 (size approximately 120 nm to 160 nm). Indication of efficiency in the virus size range from 145 nm.
The PMFT 1000 M is equipped with aerosol generators for measuring penetration with oil and salt. Measurement procedures for quick quality control (short test) or for testing according to standard (exposure test) are supplied.
Operation and automatic printout of the measurement results are therefore easy even for inexperienced users.
The measurement of total penetration and penetration via particle size is carried out with the high-precision aerosol photometer Promo LED 2300.
The size distribution of the test aerosol according to the standard is as follows:
EN 149:
Oil: Media diameter 290 nm | Geom. standard deviation 1,85 Salt: Media diameter 70 nm | Geom. standard deviation 2.5
42 CFR 84 / GB 2626:
Oil: Media diameter 200 nm | Geom. standard deviation 1.6 Salt: Media diameter 55 nm | Geom. standard deviation 1.86
Based on the measurement of the particle penetration via the particle size, the PMFT can also be used to consider the tolerances in the particle size distribution according to EN 13174-7 as min./max. penetration value. In addition, comparative values to other manufacturers are possible (option).
The comparison with other standards (42CFR84/NIOSH) is also easy with the 42CFR84 upgrade KIT.

The PMFT 1000 F tests respiratory protection particle filters better than the standards EN 143, ISO 16900-3 and NIOSH 42 CFR 84 with additional accurate analysis of filter mask efficiency for SARS-CoV-2 (size approximately 120 nm to 160 nm). Both total photometric penetration and fractional efficiency are tested e.g. the efficiency in the whole size range respectively the particle size-dependent penetration.
The PMFT 1000 F is equipped with aerosol generators for measuring penetration with oil and salt. Measurement procedures for quick quality control (short test) or for testing according to standard (exposure test) are supplied.
Operation and automatic printout of the measurement results are therefore easy even for inexperienced users.
The measurement of total penetration and penetration via particle size is carried out with the high-precision aerosol photometer Promo LED 2300. An automatic switch allows efficiency measurements without dilution up to 99.9995 %.
The size distribution of the test aerosol according to the standard is as follows:
EN 143
Oil: Media diameter ca. 160 nm | Geom. standard deviation < 2
Salt: Media diameter ca. 60 nm | Geom. standard deviation < 1.9
ISO 16900-3
Oil: Media diameter 190 nm | Geom. standard deviation 1.6
Salt: Media diameter 80 nm | Geom. standard deviation 1.6
42 CFR 84
Oil: Media diameter 200 nm | Geom. standard deviation 1.6
Salt: Media diameter 55 nm | Geom. standard deviation 1.86
Based on the measurement of the particle penetration via the particle size, the PMFT can also be used to consider the tolerances in the particle size distribution according to EN 13274-7 as min. / max. penetration value.
