CEL-440/480 Type 1 Sound Level Meter

The CEL-400 series of sound level
meters are an ergonomic, modular
interpretation of the classic
integrating instrument. They are
available in several combinations of
functionality in both IEC and ANSI,
Type 1 and Type 2 accuracy
grades, with choice of up to three
bandwidths and two types of data
The system consists of two
versions that differ in the way that
results are captured. The CEL-440
provides traditional manual
operation and storage of results at
the end of each run while the CEL-
480 is a more versatile instrument
that utilises a built-in clock to
automate data collection for both
long and short term measurement.
