We use

For ECG and ICG recording we use the Kendall ARBO H98SG ECG electrodes. [Kendal H124SG for children]

 

 

For SCL recording we use electrodes from Biopac

SKIN RESISTANCE TRANS, TP - TSD203

combined with

ELECTRODE GEL, ISOTONIC, 4 OZ - GEL101

 

You can also choose to use other snap on ECG/ICG electrodes and/or other SCL electrodes with 1,5mm touchproof plugs.
