Electro-Cap Electrodecap (standard model)

Electrodecap from Electro-Cap Inc.   Standard  10-20 Layout (19 EEG postions + GND). For reference usually separate Ear electrodes are used (E5), but you can have a reference electrode built into the cap. You would then need to specify both its position as the pin number on which it should be connected on the cap connector.  Note that this is a non-standard optioin and the usuablity depends on the EEG machine you are using and  it's cap connector configuration.

Note, you need to have a fixation method for the caps already or add it to your order. You have a choice of a Body Harness (E3), or Chin Strap (E23).
