This multiplexer allows the usage of a single PalmSens or EmStat Blue with up to 8 electrochemical cells, by switching between the different cells. A great way to raise efficiency.

A single PalmSens or EmStat Blue can be used to work with multiple working electrodes or a sensor array by means of a multiplexer. The multiplexer switches between their working electrodes in the range of milliseconds. There are two versions of the multiplexer available.

MUX8-R2 multiplexer: enables to work with up to eight 2- or 3- electrode systems.

MUX16 multiplexer: enables to work with up to sixteen 2- electrode systems. The 16 working electrodes can have a shared counter and reference electrode, or each working electrode is matched with its own combined reference/counter electrode. If only the working electrodes are switching, one reference and one counter electrode shared by all working electrodes is a possible configuration.

The MUX8-R2 is the successor of our popular MUX8. The design has been revised and improved leading to several new features.

– improved performance for OCP measurement
– reduced charge injection by switching
– all hardware settings are controlled by the software making it unnecessary to flick a physical switch
– allows to be used with the new 4-in-1 cell cables (easier and better connections), i.e MUX8 Connection Terminal is not needed
– allows to connect auxiliary input (like temperature sensor)
– LEDs to show which channel is selected
– daisy chaining multiple MUX8 boards (expansion up to 128 channels)


Standard packaging includes two double shielded Dsub cables ending in 2 mm banana plugs and a USB cable. As alternatives we can provide a PCB with screw terminals or a D-Sub cable ending in ferrules. Each of these cables can be connected to 4 channels, if all 8 channels are used, two cables are needed.

MUX8-Multiplexer für 8 Zellen

To complete your setup, we can offer you cables for connecting your electrodes or combining multiple MUX8 devices to increase the number of channels (daisy chain).
