PCE Instruments Sound level meter Data logger PCE-428-EKIT 25 - 136 dB 20 Hz - 12.5 kHz USB

Sound level meter PCE-428 including external noise Sound level meter Kit sound level meter of class II 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 of the sound level meter PCE-428 is an optimal sound level meter for measurements at work places, construction sites, in road 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. PCE-4xx-EKIT The additional kit for outdoor sound measurement PCE-4xx-EKIT can be combined with the sound level measuring devices PCE-428, 430 or PCE-432. This kit allows you to measure the external noise with a sound level meter over a long period of time. The outside noise sound meter kit consists of a waterproof Peli carrying case with rollers. In this case, a charger and two additional lead gel batteries are installed, which enable the operation of the sound level meter of up to 10 days. During the outdoor sound measurement, the case can remain closed. The external connections for the microphone and the power supply protect all electronic components from water. The scope of delivery of the outdoor noise measuring device includes a rain and wind protection as well as a wire mesh for the microphone. There is also a tripod with which the microphone can be set up outdoors. The charger of the PCE-4xx-EKIT is also waterproof. This allows the charger to remain outdoors. The outdoor noise measuring device can be used, for example, for the sound measurement of street noise, aircraft and railway noise, event noise, etc. Weather conditions do not matter, hail, snow and rain are no problem for the kit for outdoor noise. If the PCE-432 sound level meter is combined with this measuring kit, it is even possible that the exact location of the sound level measurement around the outdoor area is assigned via the GPS receiver.
