Campbell Scientific CR850 Datalogger
Campbell's CR850 datalogger can be used with your community or perimeter air monitoring, and water quality remote monitoring systems. The CR850 reads and records input from your sensors, even when it's disconnected from a power source. An integrated keyboard and display lets you program the system, manually initiate data transfers, and view data on site.
The CR850 can provide stand-alone operation in harsh or remote environments. An optional communication device like the Netronix Thiamis ICU 820 can wirelessly send data to your desktop.
