The Casella CEL242 mixes ease of use with the ability to store noise measurements and download to a computer. This Class 2 sound level meter measures the Fast and Slow sound level with "A" and "C" frequency weighting, making it ideal for basic noise surveys and alarm testing.
Unlike most sound level meters in this price range, the CEL242 uses the latest in digital technology - models using the older analog techniques tend to drift more over time and with temperature and air pressure changes. Sampling and digitizing the signal closer to the microphone ensures a much more stable sound level meter for repeatable measurements.
|The graphical display gives the option of viewing the sound level as a simple number (shown to the left) or as a graph, clearly showing the variation of noise over time (see main image).|
An AC output and optional DC output mean this meter can be connected to a level recorder, PC equipped with an A/D converter or integrated with another data logging system.
The CEL242 stores the sound level every second to its internal memory. It also stores a summary of the measurement, including start time, date, measurement duration and the maximum sound level.
The meter comes with software to download measurements in CSV format, which can be read directly into Excel or similar spreadsheet programs.
