Our CR1000 or CR3000 dataloggers store data on CompactFlash® Memory Cards via a CFM100 Compact Flash Module (purchased separately) or NL115 Ethernet Interface and CompactFlash Module (purchased separately). Data can also be stored on CompactFlash cards via the PCMCIA Card Slot in our CR5000 dataloggers, CR9000X-series dataloggers, and the CR9080 PAM Module of our CR9000 Dataloggers; a CF1 adapter is required. A PC can read/write data stored on the CompactFlash card by using either the CF1 CompactFlash adapter or ImageMate Reader/Writer.
