Real-time octave and ⅓ octave measurements
Simultaneous measurement of all parameters with all
frequency and time weightings
Class 1 or Class 2 models available
2GB memory for more than 1 year of data storage
Removable pre-amp
Environmental outdoor kit available
Data can be marked to signify any significant events, the data
from which can be removed afterwards in insight software.
Up to 60 hours of audio files can be stored, commonly used for
noise source identification. Stored audio can be played back
on the instrument using headphones or downloaded to Casella
insight software.
For unattended monitoring, event mode (CEL-633) allows trigger
levels (dB) to be set, so additional data (e.g. Leq, Lmax) is stored
together with the audio file for later play back or analysis, as well
as a profile down to 10ms intervals.

An environmental noise monitoring kit is available which protects
the instrument and microphone from the weather and allows
unattended monitoring for up 10 days.
Occupational Noise Measurements
The 63x series is designed to make workplace noise
measurements as quick and simple as possible. The displayed
information can be made as simple or comprehensive as required
and all measurement parameters are stored simultaneously, so
no incorrect measurements can be made.
When the unit is calibrated with the CEL-120 calibrator, the
calibration dates and times are stored and downloaded to Casella
insight software, validating the accuracy of measurements.
Average, peak, and octave band measurements are performed at
the same time, so only one measurement needs to be made for
all workplace noise applications.

Model Functionality
There are 2 models available, please see the model selection
table below for the one you require (e.g. CEL-632). Then
select your frequency analysis requirements by adding ‘A’ for
broadband, ‘B’ adds octave band and ‘C’ adds ⅓ octave e.g.
CEL-632C. Then add either a 1 or a 2 to denote the accuracy
class e.g. CEL-632C1. Each instrument comes complete with a
standard kit case, windscreen and calibration certificate.
For an instrument kit add /K1 to the instrument part number
e.g. CEL-632C1/K1. Instrument kits include the relevant
instrument, acoustic calibrator (CEL-120), USB download cable,
batteries, calibration certificates and an executive kit case.
