FDM10 digital noise tester is a device used for noise detection and testing in public places such as living, production, construction sites, and squares. Noise pollution is one of the most influential environmental pollution. Higher decibel noise can even cause serious damage to human eardrums, resulting in deafness, insomnia, dizziness and headaches. The application of FDM10 digital noise tester can provide the decibels reached by the noise so that relevant measures can be taken to control and reduce the noise. The measurement unit of sound is decibel. FDM10 digital noise tester has a highly sensitive sensor, high precision, wide application range, and can be widely used in noise measurement in various environments.
