Isokinetic probe
For the best accuracy in laminar flow environments, always use the
supplied isokinetic probe with this
instrument. The velocity of air in the
probe is similar to that of a typical vertical or horizontal laminar flow
environment such as a clean room or clean hood. The supplied
isokinetic probe supplies the same vertical (or horizontal) flow speed of
the air in order to collect representative samples of the clean room
laminar flow for the instrument. Refer to Figure 2 for a comparison of
sampling with and without the isokinetic probe.
