CEL240 Digital Sound Level Meter
Product Descriptions
The 24x Series has a simple user interface using two ‘softkeys’, which represent options displayed at the bottom of the screen.
This makes the instrument very easy to use and any setup changes are retained the next time the unit is switched on. To accurately measure fluctuating noise levels, the CEL-246 model measure average values, integrated over time; Leq for European Standards and Lavg for the USA. In order to quantify how noise varies with time, the CEL-246 logging variant (CEL-246 stores 419,000 data points) is also available to store the time history of the noise levels as well as the levels for the overall measurement (e.g. maximum and average levels, as detailed in
the table opposite).
