The Class 1 noise meter meets all requirements for noise measurement and frequency analysis. This integrated precision impulse noise 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 noise meter features a very large illuminated display. The display shows the sound pressure level numerically and graphically in real time. This professional noise meter features an integrated data logger. The measurement data is stored on a microSD card.
This card can be read directly into the PC. The noise meter can also be connected to the PC via USB and the memory 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 abatement measures, and estimating noise exposure.
The noise meter's pulse function 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 upgradeable. The measuring range of this professional noise meter extends from 22 to 136 dB(A) at a frequency of 3 Hz to 20 kHz.
