The dilution system VS 100 is for the defined dilution of aerosols and thus provides the possibility to conduct particle measurements even in the case of very high particle concentrations. This is done by splitting the sample volume flow into 2 partial flows whereby 99% of the actual sample volume flow is directed through a HEPA filter that absorbs virtually all particles contained in the aerosol. This means that only 0.0283 l/min. or 0.01 CFM of the sample volume is fed unfiltered to the particle counter resulting in a dilution ratio of 1:100.

Areas of application:
Adjustment of the aerosol generator to a defined particle concentration. Measurement of heavily contaminated rooms and environments.
