Noise meter-analyzer М–105
Purpose
The device is designed for measurement of A and C frequency sounds (State Standard 17187), the sound pressure level in the frequency range from 20 Hz to 20 kHz, the sound pressure level in octave and third octave bands in the frequency range from 20 Hz to 20 kHz, the spectral density of the sound pressure power the in the frequency range from 20 Hz to 20 kHz.
The noise meter is to be used for noise level measuring while operation of the industrial and household equipment and machinery, evaluation of the spectral composition of the noise measured and rapid diagnosis of investigated industrial mechanisms in products development and quality control.
Structure
The device consists of a portable measuring unit and a remote microphone with an analog-to-digital converter.
