CEL633A Sound Level Meter

Environmental Noise

The CEL633A is an Environmental sound level meter, suitable for applications that demand an accurate meter of the correct grade along with detailed measurement storage with Time History and automatic measurement timers.

This meter can be used without a computer, reading the measurements from the screen, but really benefits from having the Insight software to download the detailed time history measurements.

  • Designed for environmental noise measurements
  • Meets the required standards (Type 1 or Type 2)
  • All parameters needed: LAeq, LAmax, Ln, etc.
  • Storing and download to computer
  • Detailed time history store
  • Color coded display for ease of use

As this meter measures all parameters at the same time there is no need to select what you need beforehand. Just make the measurement and everything is there.


1. Calibration Check

The regulations and guidelines state that the meter's calibration should be checked before making measurements, and that you should keep records of these calibration checks.

Fit the Calibrator over the microphone as shown on the right and switch it on. The meter automatically detects the presence and correct fitting of the Calibrator and then starts the calibration process, which only takes a few seconds.

Calibration details are stored in the meter so that you can either make note or download them to a computer.

Manual Measurements

To start a measurement, simply press the Run/Stop key, shown on the right.

This starts the measurement and storing process for all parameters, the most important being LAeq, Lmax and Ln (L10, L90, etc). It also stores the time history of the noise, which provides a graph of the sound level over time.

When you are happy that you have measured for long enough simply press the Stop key.

Color Coded Display

The current state of the sound level meter can be seen at a glance.

When not running the meter shows the current sound level and the border is red.

When running the meter shows the measurement parameters such as Leq and the border is green.

Automatic, Repeating Measurements

For many environmental noise surveys, you need periodic (usually 5 minute, 15 minute or 1 hour) measurements showing values such as the Leq and the L90.

Setting the Timers

To make this type of measurement, set the meter to make repeating measurements of the required duration. The meter will now run for the specified period. It will then stop, store the results and start again automatically. Advanced timers even allow different measurement times for different days.

It is better to mount the meter on a tripod for this type of measurement. A tripod mount is included on the back of the meter. It can be fitted to a standard camera tripod, or we can provide you with a suitable one.
