This MicroSD card comes pre-formatted to FAT32 to work with applicable PurpleAir monitors (the Classic-SD, Flex, and Zen sensors). When you can’t connect to the real-time PurpleAir map, use this card for offline data collection. This card can store well over two years of data, although you should always check to ensure your data is being written correctly.
Only installed at remote site two weeks ago. Have not returned to site to read the card yet. My initial test using a few real time measurement points do show that I need a Rosetta Stone from you that expands the column headings. I know what the first few stand for but many I do not. Extracting and replacing the card is tedious and this time I wish Blue Tooth was a built-in. Reminder: my site lacks power and wifi router capability.

Worked fine!
Worth budgeting a little extra and getting this shipped with the unit in order to minimize hassle.
