IoT Meter with GPS PCE-432 (class 1) incl. outdoor noise level meter kit
Handheld noise meter / Octave band filter / A, B, C and Z rating filter upgradeable / Fast, Slow and Pulse Evaluation / Data logger / USB
The Class 1 IoT meter meets all requirements for noise measurement and frequency analysis. The IoT meter is equipped with a GPS receiver in addition to the sound measurement function. The GPS function allows the user to assign the measured values to an exact position.
This integrated precision pulse SPL meter follows all valid standards and guidelines (Class 1 EN/IEC 61672, ANSI S1.4-1983, ANSI S1.43-1997 EN/IEC61260, etc.) The IoT meter has a very large illuminated display. The SPL meter display adjusts the sound pressure level numerically and graphically in real time. The professional SPL meter has an integrated data logger. The measurement data is stored on a micro SD card. This card can be read directly in the PC.
Likewise, the IoT meter can be connected to the PC via USB and the memory can be read out. The post-processing software from the sound level meter allows convenient measurement data analysis. The typical applications for this instrument are the measurement of workplace noise, compliance, environmental noise detection, selection of hearing protector selection, selection of appropriate noise abatement measures and noise exposure estimation.
The pulse function of the IoT meter allows you to record short-term sound events. Thanks to the integrated octave band function even the smallest differences in the frequency band can be detected. The frequency filter can be optionally upgraded. The measuring range of this IoT meter ranges from 22 ... 136 db (A) at a frequency of 3 Hz ... 20 kHz.
PCE-4xx-EKIT
An additional kit for IoT meter can be combined with the SPL meters PCE-428, 430 or PCE-432. This kit makes it possible to measure the outdoor noise with a noise meter over a long period of time. The environmental noise monitoring system consists of a waterproof Peli carrying case with rollers. A charger and two additional lead gel batteries are installed in this case, which allows an operation of the sound monitor for up to 10 days. During the IoT meter, the case may remain closed. Due to the external connections for the microphone and the power supply all electronic components are protected from water.
The delivery scope of the IoT meter includes rain and wind protection as well as a wire mesh for the microphone. Also, a tripod is available with which the microphone can be placed outdoors. Also, the charger in the measuring kit PCE-4xx-EKIT is waterproof. So, the charger may also remain outdoors. The IoT meter can be used, for example, for the sound measurement of road noise, aircraft and train noise, event noise, etc. The weather does not matter, hail, snow and rain are no problem for the kit for outdoor noise. If the IoT meter is combined with this measuring kit, it is even possible that the exact location of the sound level metering around the outside area is assigned via the GPS receiver.
