The PMFT 1000 M tests face masks better than the standards Test of total penetration better than the standard, exact analysis of filter mask efficiency from 145 nm to 5 µm
PMFT 1000 M for reliable continuous operation in routine monitoring of half masks. Test of total penetration better than the standard, exact analysis of filter mask efficiency from 145 nm to 5 µm Both total photometric penetration and fractional efficiency are tested e.g., the efficiency in the whole size range respectively the particle size-dependent penetration.
In addition, the PMFT 1000 M meets the requirements for respirators specified by the CCF (Covid Certified Filter) quality seal .
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 13274-7 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.
