Often the
selection of a particle counter for use in a
cleanroom is done based upon the specifications and cost of the
instrument.
Before
getting into the details of the specifications it is important to look at what
the instrument will be used for, the environments it will be used in, and who
will be using the instrument. Without this information taken into consideration,
a less then optimal choice of particle counter for the application could be
made. Here are some items to consider prior to selecting a handheld particle
counter:
What type of
environment will the particle counter be used in? Will it be used in an ISO
Class 3 Cleanroom for routine particle counting or will it be used for verifying
a flow bench is operating prior to a critical process?
What type of
data is the particle counter expected to collect? Will this information be
recorded as simple pass/fail or will the information have to be logged into a
spreadsheet or database?
Will the
operator be carrying the particle counter around and placing it on a critical
work surface or will it be cart mounted?
Will this handheld
particle counter be used to certify cleanrooms and travel from location to
location?
Will the
particle counter be used to monitor the cleanroom on a continuous basis? Is the
particle counter intended to interface with a Facility Monitoring System
(FMS)?
