CEL244 Integrating Sound Level Meter

CEL240 Class 2 CEL242 Class 2 Logging CEL244 Class 2 Integrating CEL246 Class 2 Integrating Logging

The CEL244 meets the strict demands of the international sound level meter standards and is provided with a Calibration Certificate at no extra cost, so you can make your noise measurements with confidence. This is most important when using a meter in a hearing protection and conservation program.

See Specifications page for more details about the standards and noise measurement range.

Integrating Sound Level Meter

A standard (non integrating) sound level meter gives an instantaneous reading of the sound level. In an environment where the sound levels are changing continuously, as most are, it can be very difficult to average this by eye. The solution is to use an Integrating sound level meter such as the CEL244, which will give you a reading of Leq, which is the average sound level.

Due to the risk of underestimating the average sound level, especially if you fail to take into account the logarithmic nature of the decibel, many regulations advise or even demand the use of an Integrating Sound Level Meter. The UK and EU regulations and HSE guidelines state that you should use an integrating meter.

Digital Technology and Graphical Display

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).

Unlike most sound level meters in this price range, the CEL244 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.
