This is a 32k datapack with the program for the SF10 datalogger. Historical interest really, because the later SF12 software superseded it. Both the SF10 or SF12 software packs will work with either the SF10 or SF12 dataloggers.

See other listing for SF12 datapack which has improved capabilities (though the SF12 is on a 64k pack and is hence more expensive). 

Useful as a backup if you have the SF10 logger and it meets your needs!
