CEL632A Sound Level Meter

Occupational Noise

The CEL632A was designed specifically for occupational noise measurements in line with the OSHA, MSHA, ACGIH and EU regulations. It provides all the noise measurement parameters that you need in a meter of the correct grade, and also offers more detailed data logging and automatic timers for longer term detailed assessments.

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 occupational noise regulations
  • Meets the required standards
  • All parameters needed: Lavg, TWA, LAeq, LPeak
  • Storing and download to computer
  • Detailed time history store
  • Color coded display for ease of use

The full occupational noise measurement process is described below.

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.

2. Start and Stop 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 for noise at work being the Lavg and Peak. If the meter has Octave Band Filters fitted then these measurements start too.

When you are happy that you have measured for long enough (the average level has settled for example), simply press the Stop key.
