PMPD 1000

The PMPD 1000 dilution system is a dilution system according to the ejector principle that was especially developed for the PMP application or the PMP measurement chain. The PMPD 1000 achieves a dilution factor of 1:1000 (see Figure 1) by means of a thermodiluter up to 200°C.

The PMPD dilution systems offer all the advantages of the other Palas^® product series of ejector diluters, e.g. a temporally constant dilution factor.

The suitability of the PMPD 100 for the PMP measurement chain was confirmed at the METAS Institute in Switzerland (see measurement report no. 235-10383). The PMPD 1000 cascades a further dilution step as compared with PMPD 100.

VDI report no. 1973 from 2007 proved metrologically that a reproducible aerosol dilution is possible with the Palas^® dilution systems down to V_F 100,000.
