Tips: What is a noise detector?
Noise tester is an instrument used for noise detection and testing in public places such as work sites and squares. Factory noise monitoring Noise pollution is one of the environmental pollutions that have a greater impact. Higher decibel noise can even cause serious damage to people's eardrums and cause deafness. The application of the noise tester can provide the decibel that the noise reaches in order to take relevant measures to control and reduce the noise. The measurement unit of the sound level is decibels. The professional noise tester has a highly sensitive sensor, high accuracy, and a wide range of applications. It can be widely used for noise measurement in various environments. Sound level measuring instrument, collectively referred to as sound level meter.
Sound level meter with GPS, bluetooth, recording function, data storage 3 MB, measuring range 28 dB~133 dB, accuracy ±1.0, 2.6 inch color screen display, resolution 240×320, brightness can be adjusted. Portable sound level meter has the advantages of accurate reading and easy to use.
