CEL246 Sound Level Meter


The CEL246 is a data logging integrating sound level meter that meets the international standards to Type 2 / Class 2, as required by many noise measurement standards. It measures and stores the Lavg and Leq along with the Fast or Slow sound level and comes with both A and C frequency weightings.

  • USA regulations (OSHA) occupational noise surveys - Lavg
  • Canadian, European and other noise at work regulations - Leq
  • Logs the sound level every 1 second
  • Lightweight but rugged case
  • 2 year warranty
  • Calibration certificate included


  • ANSI S1.4, ANSI S1.43 Type 2
  • IEC 60651 and IEC 60804 Type 2
  • IEC 61672 Class 2

The CEL246 meets the strict demands of the international sound level meter standards and is provided with a Calibration Certificate at no extra cost, so you can make your noise measurements with confidence. This is most important when using a meter in a hearing protection and conservation program.

An AC output and optional DC output mean this meter can be connected to a level recorder, PC equipped with an A/D converter or integrated with another data logging system.

See Specifications page for more details about the standards and noise measurement range.

Integrating - Averaging Sound Level Meter

A standard (non integrating) sound level meter gives an instantaneous reading of the sound level. In an environment where the sound levels are changing continuously, as most are, it can be very difficult to average this by eye. The solution is to use an Integrating sound level meter such as the CEL246, which will give you a reading of Lavg or Leq, depending on which regulations are being followed.

Due to the risk of underestimating the average sound level, especially if you fail to take into account the logarithmic nature of the decibel, many regulations advise or even demand the use of an Integrating Sound Level Meter.

Digital Technology and Graphical Display

sound level display The graphical display gives the option of viewing the sound level as a simple number (shown to the left) or as a graph, clearly showing the variation of noise over time (see main image).

The CEL246 uses the latest in digital technology - models using the older analog techniques tend to drift more over time and with temperature and air pressure changes. Sampling and digitizing the signal closer to the microphone ensures a much more stable sound level meter for repeatable measurements.

Data Logging and Download Software

The CEL246 stores the sound level to internal memory at a rate that can be set from 1 second to 10 seconds. It also stores a summary of the measurement, including start time, date, measurement duration, maximum sound level, Lavg and Leq.

Free software is included with the meter to download the measurements and transfer into Excel or similar spreadsheet. For more information about additional software please visit the CEL246 Software page.
