CEL-63X Integrating Real Time Analyzer Series

The measurement of complex noise sources requires a complete knowledge of the noise climate over an extended time period. The CEL-63X series of 4 different analyzers is designed to satisfy this need by providing a choice of instruments to suit almost any measurement requirement. A super wide 120 dB dynamic range means that the user does not need to worry about selecting measurement scales as the meter will always be on the right range. The simultaneous provision of all the popular frequency and time weightings and exchange rates allow many different types of noise measurements to be taken by new and experienced users alike. The full-color, highprecision, graphic LCD enhances the user experience with this new meter.

Applications

For measurements of noise levels in the workplace the CEL- 630 will be the most appropriate model. It provides all the required parameters for comprehensive OSHA, ACGIH or similar studies. However, in some environmental measurement situations the statistical parameters LN% are more suited to describe the changing levels. The CEL-631 is designed to assist in the correct interpretation of these difficult outdoor noise climates. Regular periodic recording at fixed intervals is provided in the CEL- 632 model The changing noise samples are stored together with the overall time average answer and displayed annotated with the real time clock. This enables the CEL-632 to correctly record changing noise levels and enables the user to visualize the way the noise varied during the measurement. Full logging and the measurement of the LN% values is available in the CEL- 633 top of the line model. Additionally, octave and third octave band filters in the B and C versions can provide frequency analysis of tonal noise levels that are important for the correct prescription of hearing protectors or noise reduction applications.
