We do not sell electrodes, so you are welcome to use the ones you already have. The white snap holder that joins two mount pieces has a recess for a standard 10 mm gold cup on a 1.5 mm DIN lead. Most labs already have these in a drawer, from Natus, Technomed or OpenBCI. To fit one, fill the cup with paste, seat it in the holder and run the lead back to the board.
The 10 mm gold cup is the default. It is the electrode with published cat and dog evidence on unshaved heads, and it is the one we used in our own pilot. Any brand with the standard cup diameter and a 1.5 mm DIN touchproof plug will seat in the holder and plug into the lead set.
4 mm snap hydrogel electrodes fit through an adapter. Please use them on shaved ECG sites only. We have no evidence for hydrogel on unshaved fur and would not expect it to hold well.
We are not aware of any cat or dog evidence for saline sponge electrodes, and we have not tested them ourselves. If you have used them, we would be very glad to hear how it went.
