It is important to know that not all sound level meters are the same, as such, some models are not suitable for specific tasks. Sound level meters are generally split into 2 groups: Class I and Class II. Class I sound meters are a popular choice for safety professionals because they tend to have a wider frequency range and a smaller tolerance for error, hence they are more accurate than Class II sound level meters that have a smaller frequency range and a larger tolerance for error.
We supply a range of sound level meters from manufacturers such as Castle Group, Extech, Martindale, Kewtech, Testo and Tenmars to name a few.
