Class 1 SPL Meter PCE-432 with Calibrator

The class 1 sound level meter meets all the requirements for noise measurement and frequency analysis. In addition to the sound measurement function, the noise meter is equipped with a GPS receiver. The GPS function allows the user to assign the measured values ​​to an exact position.

This integrating precision pulse sound level meter complies with all applicable standards and guidelines (Class 1 EN / IEC 61672, ANSI S1.4-1983, ANSI S1.43-1997 EN / IEC61260, etc.). The sound level meter has a very large illuminated display. The display of the sound level meter shows the sound pressure level numerically and graphically in real time. The professional sound level meter has an integrated data logger. The measurement data are saved on a micro SD card. This card can be read out directly in the PC.

The sound level meter can also be connected to the PC via USB and the memory can be read out. The post-processing software of the sound level meter allows convenient measurement data analysis. The typical areas of application for this device are the measurement of workplace noise, compliance with regulations, determination of environmental noise, selection of hearing protection Protector Selection, selection of suitable noise control measures and estimation of noise exposure.

The impulse function of the noise measuring device enables short-term sound events to be recorded. Thanks to the integrated octave band function, even the slightest differences in the frequency band can be determined here. The frequency filter can be optionally upgraded. The measuring range of this professional sound level meter extends from 22 … 136 db (A) at a frequency of 3 Hz … 20 kHz.
