CEL633A1 - Product Details

This meter is ideal for detailed environmental and occupational noise surveys. With its detailed time history store (gives a graph of sound level against time) and automatic timers it is ideal for long term assessments.

The CEL633A1 provides a large set of parameters, such as "A" and "C" weighted Max, Min and Peak. As an Integrating sound level meter, it also provides the average sound level Lavg and Leq. All measurements are made in parallel, which means you do not need to decide beforehand which ones you need - they are all stored.

The meter comes complete with data logging capability. Measurements are stored in the meter's internal memory ready for download to a suitable PC.

The free CasellaDrive software can be used to import the measurements directly into Excel or a similar spreadsheet. If you want a little more than this then the Insight software simplifies the process of downloading the measurements, storing them in a database, managed by person, place or process criteria.
