Dual Channel bi-polar EEG Sensor with integrated ground reference

The Dual Channel EEG sensor with integrated ground line is great when you only need two channels of EEG but want to use three other sensors with your Vilistus-4. Taking up only one port on the Vilistus-4, the Dual Channel sensor provides two channels of data. This also means that you could attach up to FOUR people to one Vilistus-4 Digital Sampling Unit as this sensor is provided with it's own integrated ground reference cable.
