CEL632B Noise at Work Meter with Octave Bands

noise at work meter with octave bands
CEL632B Sound Level Meter


In addition to the usual measurements needed for a noise at work assessment, the CEL632B has advanced automatic timing, time history storage and real-time octave band filters.

  • Noise at Work Measurements
  • Hearing Protector Checks (SNR, HML and Octave Band methods)
  • Real-Time Octave Band Filters
  • Data Logging with detailed Time History store
  • Voice Notes and Audio Recording
  • Automatic On/Off Timers
  • Measures Leq, Lepd, Min, Max, etc. Simultaneously
  • Range: 20 to 140 dB(A)
  • Back Erase to remove unwanted noise events
  • Data Markers


  • IEC 61672 Class 1 or Class 2
  • IEC60851 and IEC 60804 Type 1 or Type 2
  • ANSI S1.4 and ANSI S1.43 to Type 1 or Type 2
  • ANSI S1.11-2004 and IEC 61260 Class 0 (Octave Band Filters)
  • UK and European Noise at Work Regulations

The CEL632B Sound Level Meter measures all the parameters needed for a successful survey of workplace noise. The main parameters - Leq, Peak, Lmax, Fast, Slow, etc. - are all measured simultaneously, so there is no need to choose before starting the measurement. With a single span from 20 to 140dB, there is also no need to choose the measurement range either.

Octave Band Filters

The octave band filters on this meter are "real-time", so it measures in all bands at the same time. The Octave Bands are particularly useful for assessing the suitability of hearing protectors for a given noise, especially when very high sound levels are present. The octave band spectrum is measured at the same time as the broadband parameters (LAeq, LCpeak, etc.) making the measurement process much more efficient.

Data Logging and Insight Software

The CEL632B comes complete with data logging capability with measurements stored in the meter's large internal memory.


When connected to a Windows computer using the free CasellaDrive software, the meter acts like a memory stick (shows as a removable drive) so the measurements can be loaded into a spreadsheet or moved to your hard drive for long term storage. There is no need to buy special software.


sound meter softwareDue to the large amount of data and the potential complexity of the measurements, we would recommend the use of the Insight software. It simplifies the process of downloading the measurements and stores them in a database, managed by person, place or process criteria. To get the Insight software for the CEL632B include item ISC020 with your order.
