The CEL-630 is simple to use and designed to meet the measurement requirements of workplace and environmental noise. It complies with the latest IEC and ANSI international standards for sound level meters. Users simply power on the instrument to automatically calibrate according to the preset and begin measurement. Regardless of the preset parameters, the CEL-630 measures all data and saves it simultaneously, so errors cannot occur.
UK casella CEL-631 Recording Octave Band Noise Analyzer Product Introduction:
UK casella CEL-631 series model selection
The CEL-630 is available in four models: CEL-630, CEL-631, CEL-632, and CEL-633. These four models can also have suffixes added to represent different configuration requirements
A represents broadband
B represents octave band
C represents 1/3 octave band
Among them, the CEL-630A series can have additional grades added, such as CEL-630A1 or CEL-630A2, where "1" represents Grade 1 and "2" represents Grade 2. Each instrument comes with a standard kit box, windshield, and calibration certificate.

Regardless of the preset parameters, the CEL-630 measures all data and saves it simultaneously, so errors cannot occur.
The CEL-630 sound level meter uses the latest digital technology with a single-range design, eliminating the need to adjust the measurement range, ensuring high-level performance under all noise sources. It can be used for environmental and/or occupational noise spectrum analysis, as well as advanced features such as data marking, timers, and historical data logging. The CEL-630 series is advanced yet easy to use.
Recording is a basic function of the CEL-630, and all models can perform voice recording. Users can speak into the microphone before and after measurements to annotate results, eliminating the need for manual recording. During measurement, data can be "marked," which also allows for recording of abnormal or important events and audio for later noise source identification. If the instrument is used unattended, recording can be triggered by a condition (such as exceeding a certain level for a period of time). In this case, additional data is also collected along with the audio. This is especially important when noise sources are transient.
