ISP 1000

Aerosol sampling unit for welas® aerosol sensors


    Exchangeable isokinetic sampling nozzles for different gas velocities
    Indicator for sample tube orientation
    Adjustable height of sampling point
    Easy installation to the welas® aerosol sensors

Description

A representative sample taking is one of the basic requirements to measure aerosols correctly with a high-quality aerosol spectrometer as e.g the welas® digital or the Promo® system. To have always a repeatable and representative sample taking, Palas® provides the sample taking system ISP 1000.

Important parameters for the sample taking are:

Important parameters for the sample taking are:

    Isokinetic suction with isokinetic inlet nozzles AIP

   The velocity at the inlet of the sample taking must be the same as the gas velocity at the point of sample taking to avoid a desmixing of the aerosol.
   The suction air flow for the welas® aerosol sensors is fixed, the inlet diameter for the isokintic aerosol sampling nozzle can be varied. Therefore Palas® offers a huge variety of different aerosol sampling nozzles AIP.
