Standard configuration

PalmSens is delivered with a shielded cable with connections for a working, a counter and a reference electrode by means of 2 mm bananaconnectors with mini-crocodile clips.

The supplied testsensor is used to test the performance of the instrument.

Extensions

PalmSens can be extended with the bipotentiostat module as well as a multiplexer with 8 or 16 channels. The opto-isolated cable as well as the Bluetooth option allows PalmSens to be used floating with respect to ground.
