FNIRSI FDM01 Digital Noise and Sound Meter 30~130dB

FNIRSI FDM01 digital noise tester is a device used for noise detection and testing in public places such as housing, production, construction sites and squares. Noise is one of the most influential environmental pollutants. Higher decibel noise can even cause serious damage to human eardrums, resulting in deafness, insomnia, dizziness and headaches. The application of FDM01 digital noise tester can provide the decibels reached by the noise so that relevant measures can be taken to control and reduce noise. The unit of measurement for sound is decibel. FDM01 digital noise tester has a highly sensitive sensor, high precision, wide application range and can be widely used in noise measurement in various environments.
