    Q & A:


    Hello, I am interested in your sound level meter. 1. is it CE marked? 2. Can you explain how data is recorded, downloaded and made available? My requirements are; a. Sound is recorded on an ongoing basis b. Data is produced on an ongoing basis based on the sound above. c. Data to be accessible as a spreadsheet and that this process is made easy. 3. Can you send me some screen shots of how data appears on your software and the requirments to run that software? Thanks, 



    The data logger itself is with CE approved.

    but its LED monitor display is not.

    The DSL-331 sound  data logger is recorded on an ongoing basis.

    Its data can be recorded and transfered to spreadsheet.
