The CEL630 is an Integrating Sound Level Meter for noise at work assessments. Fitted with a removable preamplifier (microphone stem), this meter can be used with a microphone extension cable.
Designed primarily for noise at work measurement, the CEL630 measures the "A" and "C" weighted average sound level (LAeq and LCeq) simultaneously, along with both Fast and Slow time response sound level. This means there is no need to decide what parameters are needed before making a measurement, just press go and everything is stored. This meter also has a single measurement range from 20 to 140dB, so you don't even have to select the range before starting.
The meter can be fitted with Octave or 1/3 Octave Band Filters. For noise at work measurement Octave Band Filters are the most common, as these measurements can be used to make a more accurate calculation of the sound level at the ear when wearing different hearing protectors.
Octave band filters are not essential for occupational noise measurements and are not required by most standards. However, we recommend the use of Octave Band measurements for extremely high noise levels as this is the most accurate way to assess the suitability of the hearing protectors available.
The 1/3 Octave Band Filter option is useful if you need to make a more detailed frequency analysis of machinery noise, particularly where tonal noise is a problem. Meters fitted with 1/3 Octave Bands also have single Octave Bands.
The CEL630 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.
If you want a little more than just loading the measurements into a spreadsheet then the Insight software simplifies the process of downloading the measurements, storing them in a database, managed by person, place or process criteria. To get the Insight software for the CEL630 include item ISC020 with your order.
