Casella CEL-633A Sound Level Meter

The CEL-632A Sound Level Meters is the most versatile of meters available; ideal for noise at work applications (ISO9612, OSHA) and environmental noise monitoring. Features ensure compliance with workplace noise legislation and are designed to meet the diverse needs of professionals in occupational, industrial and environmental noise monitoring applications.

For workplace noise, the CEL-633A Sound Level Meter is designed to make measurements as quick and as simple as possible. The displayed information can be made as simple or comprehensive as require,  and all measurement parameters are stored simultaneously, so no incorrect measurements can be made. When the unit is calibrated with the CEL-120 calibrator, the calibration dates and times are stored and can be downloaded to Casella insight software, validating the accuracy of measurements. Average and peak measurements are performed at the same time, so only one measurement needs to be made for these workplace noise applications. 

For environmental noise measurements, statistical data (Ln%) can be stored in broadband. Data can be marked to signify any significant events, the data from which can be removed afterwards in insight software. Up to 60 hours of audio files can be stored, commonly used for noise source identification. Stored audio can be played back on the instrument using headphones or downloaded to Casella insight software. Data markers and back-erase functionality is also included.

For unattended monitoring, event mode (CEL-633) allows trigger levels (dB) to be set, so additional data (e.g. Leq, Lmax) is stored together with the audio file for later play back or analysis, as well as a profile down to 10ms intervals. An environmental noise monitoring kit is available which protects the instrument and microphone from the weather and allows unattended monitoring for up 10 days.

Up to 60 hours of audio files can be stored, commonly used for noise source identification. Stored audio can be played back on the instrument using headphones or downloaded to Casella insight software. Data markers and back-erase functionality is also included. 

Available as a single unit or as part of a kit.
