SOUND LEVEL METER WITH DATA LOGGING INTEGRATING/LEQ MODEL CEL-246 .
The CEL246 is a data logging integrating sound level meter that meets the international standards to Type 2 / Class 2, as required by many noise measurement standards. It measures and stores the Lavg and Leq along with the Fast or Slow sound level and comes with both A and C frequency weightings.
USA regulations (OSHA) occupational noise surveys - Lavg Canadian, European and other noise at work regulations - Leq Logs the sound level every 1 second Lightweight but rugged case Calibration certificate included
Standards
ANSI S1.4, ANSI S1.43 Type 2 IEC 60651 and IEC 60804 Type 2 IEC 61672 Class 2
Integrating - Averaging 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 CEL246, which will give you a reading of Lavg or Leq, depending on which regulations are being followed.
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.
