# If running my F-9xx continuously, how many days of measurements can the 16GB SD card hold?

The 16GB card provided with the F-9xx gas analyzers technically has indefinite storage capacity as the files can be moved off the card to reopen storage space. However, without moving any files off the card, it can hold up to ~60 million measurements from a F-9xx analyzer. If the instrument is saving data every minute that equates to ~40,000 days of measurement before the SD card is full.
