CEL240 - Product Details

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 the protection of workers (hearing protection) or any other legal purposes. The CEL240 meets the strict demands of ANSI S1.4, IEC 60651 and IEC 61672 and is provided with a Calibration Certificate at no extra cost, so you can make your noise measurements with confidence.

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.

This meter can be upgraded to have data logging or Integrating facilities, protecting your investment should you need these in future.
