CEL-600 Series Digital Sound Level Meters
Think Environment Think Casella
The CEL-600 series sound level meters
use the latest digital technology to give
standards of performance never seen in
such a compact design.
Using a high resolution colour TFT display,
the CEL-600 series is specifically designed
to ensure taking noise measurements is
quick and easy.
Different models are available depending
on your requirements for use in general
workplace noise measurements,
up to full industrial hygiene
requirements where
octave band analysis
is required for the
effective selection of
hearing protection.
Key Features:
 Compact, rugged design
Simple operation
Single large measurement range
Large memory
High resolution colour display
Real-time octave band analysis
Simultaneous measurement of all workplace noise parameters
Instrument menu in 7 languages
Pre-defined and user configurations available
Automatic calibration function
Long battery life
Applications:
Workplace noise assessments
Selection of hearing protection
Calculation of noise exposure
Ensuring compliance with workplace noise legislation
Machinery noise tests
High Resolution Colour Display
Unique colour coding of measurements
Bright backlight
View in all light conditions
The CEL-600 series uses colours of the high-resolution display to aid
the user in making measurements. Measurement screens are colour
coded depending on the mode of operation. For example, during a
measurement run, the header and footer of the display is green (shown
right), whereas when a run is stopped they are red, similar to traffic
lights for 'stop' and 'go'.
Measured parameters are displayed in
different colours, and the bar graphs are
illustrated with the same colours to give an
easy understanding of the noise climate.
Simple Operation
Intuitive menu structure
Multilingual user interface
Predefined and user selectable setups
The CEL-600 series was designed with ease of use in mind. The
menu structure is designed to pick up and use without the use of
a manual. A simple icon structure is used with word prompts for
each selection, available in seven languages.
The instrument has six selectable setups. Four pre-defined setups
can be used to satisfy local workplace noise legislation. Two user
setups can be defined to display parameters and weightings
as required. Regardless of the setup used, the CEL-600 series
measures and stores all parameters and weightings even if not
selected. These can be viewed if necessary on the software.
Up to 100 measurements can be
stored without the need to download.
All runs are date and time stamped.
When connected to
a PC via the USB
connection, the
CEL-600 series acts
like a memory card,
so data files can
be moved to a PC
and easily reviewed
without the need for
proprietary
software.
Digital Technology
Large measurement range
Simultaneous measurement
Automatic calibration
Real-time octave band analysis
By using Digital Signal Processing (DSP) technology, the
CEL-600 series measures all the workplace noise parameters
simultaneously with necessary time and frequency weightings,
preventing incorrect setup of the instrument. The instrument has
a single large measurement range of 20-140dB, eliminating the
need to change measurement range and preventing errors.
On the CEL-620B model, octave analysis is performed in real-time,
saving time compared to performing measurements sequentially.
Octave band results
are shown in both
bar-graph and
tabular form with
the dominant
frequency highlighted.
Time history of the
broadband noise
level is displayed in
real-time, so a user
can see how the
noise level varies
with time.

Instrument Range
Range of instruments available
Future proof upgrade ability
Complete measurement kits
All models available in Class 1 or Class 2
The CEL-600 series comprise of the CEL-610, CEL-620A
and CEL-620B. The CEL-610 measures instantaneous and
maximum sound pressure levels. CEL-620 models are also
integrating so measure average noise levels as well as peak
levels for workplace noise legislation. CEL-620A model also
simultaneously measures the LC and LA used within the HML
method for the selection of hearing protection. In addition, the
CEL-620B model performs real-time octave band analysis from
16Hz to 16kHz, values which are used in the octave band method
for selection of hearing protection.
If future requirements Automatic calibration
change, any instrument can
be upgraded to a higher
model without returning
to Casella.
Complete measurement kits are
provided with an acoustic calibrator
in a robust kit case complete with
instruction manuals and calibration
certificates.
