The Casella CEL242 mixes ease of use with the ability to store noise measurements and download to a computer. This Type 2 sound level meter measures the Fast and Slow sound level with "A" and "C" frequency weighting, making it ideal for basic occupational 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).|
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.
CasellaDrive Software - When the meter is connected to the computer's USB port, this free application causes it to act like a memory stick, giving direct access to the measurement files. These are in the standard CSV format that can be loaded directly into Excel or similar program. More details...
dB24 Software - This optional application displays the sound level in real-time on your computer screen. It can also store the sound level to disk every second. This can be useful for continuous noise monitoring where long term records are needed.
