Solutions for Risk Reduction
Using a high resolution colour TFT display, the 62X 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.
High resolution colour display
• Unique colour coding of measurements
Octave band
measurement screen
• Bright backlight
• View in all light conditions
The 62X 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 62X 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.
Set-up selection
Multi-lingual user interface
Digital technology
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 62X 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
62X series acts like a memory card,
so data files can be moved to a
PC and easily reviewed without the
need for proprietary software.
• Large measurement range
• Simultaneous measurement
• Automatic calibration
Tabular octave results
Time history display
Instruments range
By using Digital Signal Processing
(DSP) technology, the 62X 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.
• Range of instruments available
• Future proof upgrade ability
• Complete measurement kits
• All models available in Class 1 or Class 2
Automatic calibration prompts
you to select the calibration routine
All 62X models are 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 CEL620B 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 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.
