The CEL244 and CEL620 sound level meters are available from NoiseMeters Inc.
These meters are ideal for noise assessments in factories, power stations, construction sites, all the usual places with high levels of industrial noise. With the Octave Band Filters option, the measurements can be used to select the most suitable hearing protectors.
All the advanced features (octave bands, etc.) can be added at a later date if not included in the initial purchase.
The CEL246 is intended for basic noise surveys and acoustic testing (alarms, etc.) that need a very accurate and repeatable measurements.
If bought without Data Logging, it can be easily added at a later date. This meter does not measure the Peak Sound Level, so if you have any chance of loud banging noise you should consider the CEL620 described blow.
The CEL620 Series are all Integrating Sound Level Meters. These meters provide you with the Leq, Peak and LEP,d, which are the main parameters for a noise at work assessment. This is a data logging meter with options are available for Octave Band or 1/3 Octave Band Filters (for hearing protector assessments and detailed machinery noise checks).
Real-time octaves are an option for the CEL620 Sound Level Meter. As with most options for this meter, they can be added at a later date if you are not sure at the initial time of purchase.
The filters in the CEL620 are Real-Time. Also known as Parallel Filters, this means that all filters are operating at the same time, making the measurement process much easier and quicker than the lower cost serial filters available on many other meters.
The CEL620 is a data logging sound level meter. When connected to a computer it acts like a memory stick, allowing you to load the measurements into Excel or similar software, or to copy the measurements to your computer for long term storage.
If you want a little more from the meter then the Insight software will download the measurements, store them in a database, link them with person, place or process and ultimately generate occupational noise reports.
