Expanded range
July 1st 2009 Casella says the introduction of the
CEL-242 and CEL-246 brings new
capability to its CEL-200 series of
sound level meters. The
new models can store
time history onto an
onboard memory
capable of logging over
400,000
measurements.
Data is stored as files compatible with
spreadsheet software packages (.csv
format) and can simply be
transferred via USB then graphed as
required with any standard package.
The CEL-200 range can display a
non-decaying maximum hold value
on a number of screens showing the
A or C frequency weighting and
slow, fast or Impulse time responses.
The time history facility shows how
the noise has fluctuated and allows
users to understand at what point
noise control measures are necessary.
The equipment has a large, highresolution
display which show results
either numerically or by bar graph
and can give a time history trace
over the last 1 or 5 minute period. More articles from Casella Measurement: |
