The CEL632C is a data logging sound level meter for detailed occupational noise surveys. It includes automatic timers and a Time History store, making it ideal for longer term and unattended measurements. The real-time octave band filters provide the measurements for a detailed check of hearing protector suitability, and 1/3 octave band filters give a more detailed frequency analysis of machinery noise.
The CEL632C Sound Level Meter measures all the parameters needed for a successful survey of workplace noise. The main parameters - Lavg, Leq, Peak, Lmax, Fast, Slow, etc. - are all measured simultaneously, so there is no need to choose before starting the measurement. With a single span from 20 to 140dB, there is also no need to choose the measurement range either.
The Type 1 Noise Measurement Kit (CEL632C1-K) is supplied in a tough Peli Case with custom foam to protect the meter, calibrator and accessories. More details...
Rea-time Octave and 1/3 Octave Band Filters are included with this meter. Octaves are particularly useful for assessing the suitability of hearing protectors for a given noise, especially when very high sound levels are present. The CEL632C measures in all bands at the same time as these are "real-time" filters. In 1/3 Octave Band mode, the meter splits the spectrum up into smaller bands (three for each octave) for a more detailed analysis of the spectrum.
The CEL632C comes complete with data logging capability with measurements stored in the meter's large internal memory.
When connected to a Windows computer using the free CasellaDrive software, the meter acts like a memory stick (shows as a removable drive) so the measurements can be loaded into a spreadsheet or moved to your hard drive for long term storage. There is no need to buy special software.
Due to the large amount of data and the potential complexity of the measurements, we would recommend the use of the Insight software. It simplifies the process of downloading the measurements and stores them in a database, managed by person, place or process criteria. To get the Insight software for the CEL632C include item ISC020 with your order.
