The PalmSens instrument is a battery-powered and handheld potentiostat / galvanostat which allows the application of most of the relevant voltammetric and amperometric techniques.
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 opto-isolated cable as well as the Bluetooth option allows PalmSens to be used floating with respect to ground.
