Cadwell's bar electrodes have a large body for increased stability and solid, machined contacts (spaced 3 cm center-to-center) to resist the wear and tear of repeated cleanin. Polarity indicators are molded into the body. The convenient, snap-on handle fits our bar electrodes for ease of handling. See chart below for Shielded and Unshielded configurations.
Replacement felt pads are single use only.
