BLUETOOTH & BATTERY MODULE


The iBlue is a simple plug&play module that contains a battery pack for powering the pocketSTAT2 and at the same time provides a Bluetooth
connection between the instrument and your computer.
This is ideal for using the pocketSTAT2 in awkward and difficult to reach places. The battery pack operates the pocketSTAT2 for > 5 hours; it is compatible with all models of pocketSTAT2.
