Can the data be output - CSV format? Does it store to a removable data card?

The R8080 records up to 64k readings to internal memory.  The recorded data can be viewed using the free software and data can be exported from there as a .CSV file.

The R8080 doesn’t use an SD card or any other removable memory card. 

 If you would like something that records data to an SD card you should look at the Reed R8070SD - https://microdaq.com/reed-sound-level-data-logging-meter.php
