CEL-633-C2-K2 Sound Level Meter Type 2 Printer Kit with Standard Accessories Including Insight Database Software by Casella

Noise measurements from complex sources require a complete knowledge of the variable noise climate over an extended period of time. The CEL-633 model is designed to satisfy this need by providing overall, periodic and profile time history recording to suit almost any industrial or environmental measurement requirement.

A super wide 120 dB dynamic range means that the user does not need to worry about selecting scales as the meter will always be on the right range. The provision of all the popular frequency and time weightings simultaneously allow many different noise measurements to be taken by new and experienced users alike. The fullcolor, high-precision, graphic LCD enhances the user experience with this new meter. Audio recording is possible.

Key Benefits

  • Wide dynamic range from 20 to 140 dB on single span
  • A, C and Z simultaneous frequency weightings
  • Slow, Fast and Impulse rms. time responses
  • Large 240 x 320 pixel color VGA graphic display
  • Easy to use menu structure
  • Optional data logging capability (model specific)
  • Regular timed or event triggered recording possible (model specific)
  • Available in ANSI/IEC class 1 and class 2 accuracy
  • Available with real time octave & 1/3 octave band filters plus 3 broad band results A, C & Z
  • Storage of all results simultaneously in a huge non-volatile memory
  • Period and time history profile recording
  • Noise event recording

Applications

For measurements of outdoor noise levels over extended periods of time the CEL-633 will be the most appropriate model. It provides all the required parameters for comprehensive EPA, HUD or similar studies. It provides the popular max, min, and time average levels in addition to the statistical or LN% parameters. The CEL-633 is designed to provide all the key results for these difficult environmental noise climates. Regular periodic recording at fixed intervals is provided in the CEL-633 model plus the addition of extra time history profile recording. The changing noise intervals are stored with the overall time average answer and displayed annotated with the time they occurred. Significant events can be triggered by noise level exceedances providing even more detail about what has happened. The audio signature is captured and can be used to identify the cause. 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.
