Reference & Ground Electrodes
Ag/AgCl reference electrodes and grounding hardware for a stable baseline and noise rejection.
Reference & Ground Electrodes
Ag/AgCl pellet and wire reference electrodes, plus ground screws and pre-soldered wire, for stable DC baseline and common-mode noise rejection in acute and chronic setups.
Reference & Ground — FAQ
Setting a stable baseline and rejecting noise.
Reference vs. ground — what's the difference?
The ground sets the animal to the amplifier's common; the reference is the baseline each channel is measured against. A bad ground is a common source of noise.
Why Ag/AgCl?
Ag/AgCl electrodes hold a stable half-cell potential, giving a low-drift DC baseline for reliable referencing across a long session.
