The Class 1 PCE-432 sound level meter meets all requirements for noise measurement and frequency analysis. In addition to its sound measurement function, the noise meter is equipped with a GPS receiver. The GPS function allows the user to assign the measured values to a precise location.
This integrated precision impulse sound level meter complies with all applicable standards and guidelines (Class 1 EN/IEC 61672, ANSI S1.4-1983, ANSI S1.43-1997 EN/IEC 61260, etc.). The PCE-432 sound level meter features a very large, illuminated display. The display shows the sound pressure level numerically and graphically in real time. This professional sound level meter features a built-in data logger. The measurement data is stored on a microSD card. This card can be read directly from the PC.
The sound level meter can also be connected to a PC via USB and the memory can be read out. Typical applications for this device include measuring workplace noise, compliance with regulations, environmental noise assessment, selecting hearing protection (Protector Selection), selecting appropriate noise control measures, and estimating noise exposure.
The pulse function of the PCE-432 noise meter allows you to record short-term sound events. The integrated octave band function allows even the smallest differences in the frequency band to be detected. The frequency filter is optionally available via upgrade. The measuring range of this professional sound level meter extends from 22 to 136 dB(A) at a frequency of 3 Hz to 20 kHz.
