CASELLA CEL633 A1 Portable Sound Level Meter

The CEL-63x Series of sound level meters are the most versatile of meters available; ideal for both noise at work applications (ISO9612, OSHA) and environmental measurements.  
Ensure compliance with workplace noise legislation with the CEL-633 and assist with the selection of hearing protection.  For environmental noise monitoring, the CEL-633 can be used for boundary noise assessment or noise nuisance complaints. 

For Occupational Noise:
- Simultaneous measurements of all workplace noise parameters
- Standard set-ups for workplace noise legislation
- Measures parameters for hearing protection by the SNR, HML or Octave band method
- Analyze time history of noise levels
- Optional high range microphone up to 165dB

Easy To Measure and Record
The CEL-63x Series is designed to make measurements as simple as possible and displayed as simply or as comprehensively as you require – all parameters are stored so you can view as your requirements demand.

Simple to Calibrate
Simply calibrate the CEL-63x in the field with the CEL-120 calibrator with date and times stored for compliance to legislation.
Multiple Measurements
Average, Peak and Octave Band Measurements are performed simultaneously so no need for multiple measurements.  All are displayed graphically on the full color display.  There is even an option to record voice notes to trace the run.

For Environmental Noise
- Simultaneous broadband and frequency measurement
- Data Markers
- Back erase function
- Real-time frequency analysis
- Single Measurement Range
- Triggered event capture

Audio Storage
Data can be marked to signify important events which can be analyzed later.  Up to 60 hours of audio files can be stored for noise identification purposes.  Stored audio can be played back on the instrument with headphones or via Insight data management software.

Trigger Levels For Remote Monitoring
For unattended monitoring, event mode in the CEL-633 allows trigger levels to be set, so additional data (Leq, Lmax) is stored together with the audio file for later play back or analysis and the profiles go down to 10ms intervals.
