Description
Sound level meter with class II sound calibrator sound level meter with octave filter or 1/3 octave filter for frequency analysis / USB interface / data logger / A, B, C, Z evaluation / Fast, Slow and pulse analysis The PCE-428 sound level meter is an optimal sound level meter for measurements at work places, construction sites, traffic, airports, etc. The sound level meter is a class 2 device and is equipped with an octave band frequency filter. Optionally, the PCE-428 sound level meter can be upgraded by a 1/3 octave band filter. In addition to the numerical display of the measured value, a graph can show the progression of the sound level. The sound level meter has different frequency ratings such as A, B, C and, For Example, the sound meter can also display measurements with the time ratings Fast, Slow, Pulse 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 measuring profiles can be stored on the sound level meter. Here, the user can decide which parameters the sound level meter should record. Here, for example, you can choose between Laeq, LcPeak, LaFmax, LaFMin, etc. The peaking function in the sound level meter allows the maximum sound pressure level to be recorded and frozen in the display during a long-term measurement. A 24 bit AD converter and the specially developed electronics of the sound level meter contribute to the reduction of the inherent noise to a very low level. A sampling of the measuring signal with more than 48 kHz enables a high accuracy and improved stability of the measured value on the sound level meter.
