PalmSens handheld potentiostat / galvanostat
The opto-isolated cable as well as the Bluetooth option allows PalmSens to be used floating with respect to ground.
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.
PalmSens can be extended with the bipotentiostat module as well as a multiplexer with 8 or 16 channels.
The PalmSens and bipotentiostat boards are available as OEM potentiostat for other companies for instance for use in an SECM or SPR instrument.
