CEL-630 - Integrating Octave Band Digital Sound Level Meter

Just switch on the instrument, auto-calibrate and start measuring with one of the predefined views. Regardless of the view selected, all data is measured and stored simultaneously so no mistakes can be made. By implementing the latest digital technology, the meter has a single measurement range so no adjustment is required, ensuring the highest levels of performance with all noise sources.

Models are available for both environmental and/or occupational noise with the availability of frequency analysis and advance functions such as data markers, timers and logging of time history data. Even with such advanced functionality, the CEL-630 Series remains very simple to use.

• Ideal for environmental or occupational monitoring.
• Easy to use switch-on-and-go functionality.
• Latest digital technology with a high resolution colour TFT display.
• Pre-configured setups for occupational and environmental measurements.
• Single measurement range up to 140dB, no range adjustment required.
• Data markers and back erase function.
• Real-time octave & 1/3 octave measurements.
• Simultaneous measurement of all parameters with all frequency and time weightings.
• Class 1 or Class 2 models available.
• 1GB memory for more than 2 ½ years of storage.
• Removable pre-amp.
• Environmental kit available.

The CEL-630 could not be simpler to use. Just switch the instrument on and it will automatically power up into the setup last used, then go straight to the measurement screen. All screens are colour coded so you know where you are, for example green when measurements are taking place, red when stopped and blue in set-up screens. Significant events can be ‘marked’ and annotated later via Casella insight data management software. Any erroneous measurements can be removed with the back erase function, preventing any need to repeat the measurement.

Standard data ‘views’ are provided to conveniently display the noise parameters which are specified for workplace or environmental noise standards with customisable views if necessary. Regardless of the view selected, the CEL-630 Series will store all measurement parameters, giving the confidence that no mistakes can be made as all other parameters can be viewed later. Logging models (CEL-632 and CEL-633) provide 2 levels of time history storage; periods at 1 minute to 1 hour and profile data from 1 second to 30 minutes. The time history can be analysed and recalculations performed via insight software (see screenshot right). Environmental parameters (Ln%, e.g. L90) are stored additionally on CEL-631 and CEL-633 models, both in broadband and octave modes as appropriate.
