Description
The sound level meter PCE-428is an optimum sound level meter for measurements at work places, construction sites, in traffic, airports, etc. The sound level meter is a class 2 device and is equipped with an octave band frequency filter. Optionally the sound level meter PCE-1/3 can be upgraded by a five octave band filter. In addition to the numerical display of the measured value, a graph can also indicate the course of the sound level. The sound level meter has different frequency assessments such as A, B, C and Z.
Furthermore, the sound measuring device can display measurements with the time assessments Fast, Slow, Impulse and Peak. The measuring range of the sound level meter is 25 ... 136 DBA at a frequency of 20 Hz ... 12.5 kHz. 3 different measurement profiles can be stored in the sound level meter. Here the user can decide which parameters the sound level meter should detect. For example, you can choose between Laeq, LcPeak, LaFmax, LaFMin, etc.
The peak-hold function in the sound level meter enables the maximum sound pressure level to be recorded during a long-term measurement and to freeze on the display. A 24 bit AD converter and the specially developed electronics of the sound level meter help in reducing the intrinsic noise to a very low measurement. A sampling of the measuring signal at more than 48 kHz makes possible a high accuracy and improved stability of the measured value on the sound level meter.
