CEL240 Sound Level Meter
It is essential that a sound level meter meets these standards if it is to be used for any important measurements, particularly those that involve any other legal purposes. The CRL240 meets the strict demands of IEC 61672, IEC 60651 and ANSI S1.4 and is provided with a Calibration Certificate at no extra cost, so you can make your noise measurements with confidence.
See Specifications page for more details about the standards and noise measurement range.
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 CEL240 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.
