Class 1 or Class 2 Sound Level Meter?

A Class 1 sound level meter is a little more accurate than a Class 2 model. Many environmental noise regulations, and the authorities controlling them, demand the use of a Class 1 sound level meter for this type of application. Check with your regulations first. If you have any doubts then a Class 1 meter is the safer option, as you are not left explaining why you used the less accurate model. If in doubt, contact us on info@noisemeters.co.uk for advice.

Sound Level Meter Configuration

Octave Bands	With this option fitted, the meter splits the spectrum into 11 bands to provide information about the frequency content. These can be useful if you are also carrying out occupational noise measurements too.
1/3 Octave Bands	In this case the spectrum is split into 33 bands, giving a more detailed frequency analysis. Very useful for specialist applications and to get a more detailed picture of the frequency content of the noise.

Insight Software

The CEL633 is a data logging meter that does not require any additional software - when plugged into a computer it acts like a memory card. You can manually copy the data to your computer or load it into a spreadsheet program using a small conversion application. However, the Insight software makes this process more convenient, links the measurements to person, place or process, and presents the results graphically.

We recommend the Insight software with the CEL633 if you are going to take advantage of the Time History store or if you have Octave or 1/3 Octave Band Filters fitted. In these cases processing the large amounts of data in a spreadsheet can be rather time consuming.
