CEL-553 Real Time Analyzer

Introduction

The CEL-553 model is the starting point in the range of CEL real time analyzers. The instrument is available with both full octave and third octave band filters that operate simultaneously across the whole audio spectrum. Manually controlled measurements allow the operator to use the analyzer for 'Snapshot' recording in a familiar point and shoot mode associated with more standard sound level meters.

Applications

  • Workplace noise surveys
  • Product noise reduction
  • Sound power measurements
  • General acoustic engineering investigations

Operation

The CEL-553 real time analyzer uses the concept of 'Runs' and 'Records' to make measurements where the operator is in complete command of the data capture. Up to 999 separate runs can be stored in the instrument memory and each run can save up to 9999 individual measurements. A run can then represent a measurement around a particular machine with the records representing the individual measurement positions associated with that machine. The run concept logically groups the individual measurements together for easy comparison when recalled from memory or downloaded to a PC.
