cel633c environmental sound meter with 1/3 octave band filters
CEL633C Sound Level Meter

Overview

The CEL633C is highest specification sound level meter in the CEL630 range. It is ideal for measuring environmental noise in communities and around the perimeter of industrial sites, including those with a tonal noise problem.

  • Environmental Noise Surveys
  • BS4142 Mixed Residential and Industrial Noise
  • Noise at Work Assessments
  • Real-Time Octave and 1/3 Octave Band Filters
  • Data Logging with Time History Noise Profile stores
  • Voice Notes and Audio Recording
  • Automatic Timers
  • Measures Leq, Min, Max, Ln, etc. Simultaneously
  • Range: 20 to 140 dB(A)
  • Data Markers and Back Erase
  • Weatherproof Outdoor Kit available

Standards

  • 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 and 1/3 Octave Band Filters)

The CEL633C sound level meter is available as either Class 1 or Class 2 - the most common for environmental noise measurement and more accurate being Class 1. This meter also has everything needed for noise at work measurement in line with the EU regulations, making it ideal for anybody involved in both environmental (outside the factory) and occupational (inside the factory) noise.

If the meter is to be left unattended in poor weather conditions then the Outdoor Kit should be used to offer protection against the elements. The Outdoor Kit also includes a rechargeable battery pack for longer term monitoring.

Average Sound Level and Statistical Parameters

The CEL633C has a very wide span, covering 20 to 140dB in a single range. This is particularly important when monitoring in an environmental with generally low noise levels and occasionally high ones - for example when cars pass. The most useful parameter when measuring environmental and community noise is the Leq, the average sound level. The meter measures the periodic Leq and also includes five Ln values for statistical analysis of the noise.

Octave and 1/3 Octave Band Filters

The meter is fitted with real-time Octave and 1/3 Octave Band Filters, which are sometimes needed for noise sources that may tonal, such was wind turbines. As well as measuring the Leq and Lmax in each band, the CEL633C meter also measures the statistical parameters, Ln, in each of the Octave bands.

Data Logging and Insight Software

The CEL633C comes complete with data logging capability with measurements stored in the meter's large internal memory.

CasellaDrive

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.

Insight

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 CEL633C include item ISC020 with your order.


Our Recommendation

Most environmental noise surveys demand the use of a Class 1 Sound Level Meter that can make repeating measurements, such as the 5 minute LAeq and L90 (background noise), as required by BS4142 and related regulations. We recommend the CEL633C1 Class 1 Sound Level Meter for most situations, including those where tonal noise is present or a frequency analysis is required by the regulations.

Most applications demand the use of a Calibrator to check the function of the meter, so we recommend the CEL120/1 Calibrator.

Finally, we also recommend the Insight software to ease download and processing. If unsure, Insight can be easily added at a later.
