This RS PRO digital sound meter, or noise level meter, takes accurate readings of ambient noise levels in an environment. There are several reasons you might want to monitor an environmental noise level- from performance analysis to health and safety concerns. In a factory environment that uses heavy machinery, for example, you might want to know if the environment requires employees to use hearing protection. Alternatively, an entertainment venue might want to measure the noise of its sound system to see if it adheres to local noise level compliance. Digital sound level meters are often used in;

• Car industry
• Mechanical industry
• Leisure and music

What is the difference between Class 1 and Class 2 sound level meters?

Generally, Class 1 noise meter devices are able to measure a wider frequency range than Class 2, and so are more suitable for precision applications. However, for most purposes, a Class 2 device offers a potentially more cost-effective noise measurement solution.


RS PRO aims to be your go-to brand when it comes to reliability, quality, and affordability. We source high-quality tools and parts from trusted sources and employ expert testing to build a brand you can rely on.
