The CEL-633C series is an easy to use instrument designed to undertake the measurement requirements of workplace and environmental noise. It also complies with the latest IEC and ANSI international standards for sound level meters. Just switch on the instrument, auto-calibrate and start measuring with one of the predefined views. Regardless of the view selected, all data is measured and stored simultaneously so no mistakes can be made.

By implementing the latest digital technology, the meter has a single measurement range so no range adjustment is required, ensuring the highest levels of performance with all noise sources. The CEL-633C can be used for environmental and/or occupational noise with the availability of frequency analysis and advance functions such as data markers, timers and logging of time history data. Even with such advanced functionality, the CEL-633C Series remains very simple to use.

Audio recording is a standard feature of the CEL-633C, all models having a voice notes capability. This allows you to speak into the microphone before or after a measurement in order to annotate the result, so you don't need to write things down. Data can also be 'marked' during a measurement to signify either an anomalous or significant event and audio is also recorded for later noise source identification. If the instrument is used for unattended measurements, audio recording can be triggered by a condition such as a given level being exceeded for a period of time. In this case additional data will be collected along with the audio. This can be especially useful where the noise source of interest is transient.

When the unit is calibrated with the CEL-120 calibrator, the calibration dates and times are stored and downloaded to Casella insight software, validating the accuracy of measurements. Average, peak, and octave band measurements are performed at the same time, so only one measurement needs to be made for all workplace noise applications. Data can be marked to signify any significant events, the data from which can be removed afterwards in insight software.

Type 1 Sound Level Meter

Meets ANSI type 1 requirements

Store Data Results

Results can be downloaded into the Casella Insight Software. Records can be manipulated, such as changing the governing body from ISO to OSHA.

Cumulative or Periodic Mode

A cumulative measurement produces a single set of results for the entire measurement duration. The cumulative data set alone does not provide time history information. To include time history information for the measurement, you can enable Profile recording.


Periodic measurements allow the total measurement duration to be divided into separate fixed time intervals. In Periodic mode, a full set of results is stored at the end of each time interval, whereas in Cumulative mode a single full set of results is stored at the end of the measurement run. You can set the Periodic Interval to one of the following: 1, 2, 5, 10, 15, 20, 30 or 60 minutes; 2, 4, 6, 8, 12 or 24 hours

Profile Recording

The profile recording supports a more limited set of functions, including LAeq, LAIeq, LCpk, LAFmax, LASmax, LAImax, and optional Ln% statistics (Broadband Fast A-weighted Lns only). When you use profile recording, you can set the interval of each of the profile measurements to one of the following: OFF; 1, 2, 5, 10, 15, 20, 30, 60 seconds; 2, 5, 10, 15, 20, 30, 60 minutes
