The CEL-63x Series of sound level meters are the most versatile of meters available; ideal for both noise at work applications (ISO9612, OSHA) and environmental measurements (BS4142). Ensure compliance with workplace noise legislation with the CEL-633 and to assist with the selection of hearing protection.

The CEL-633 is an easy to use instrument designed to undertake the measurement requirements of the 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. Models are available for both environmental and/or occupational noise with the availability of frequency analysis and advanced functions such as data markers, timers, and logging of time-history data. Even with such advanced functionality, the CEL-630 Series remains very simple to use.

Audio recording is a standard feature of the CEL-633, 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. The Type 1 microphone can be changed out.
