These individually packaged, pre-gelled electrodes have foam backing and high-quality hypoallergenic adhesive. The low-impedance gel reduces the possibility of skin irritation while delivering immediate baseline stability. The electrode is a true silver/silver chloride (Ag/Ag/CL), ensuring reliable performance with clear, stable ECG tracings. The flexible foam base conforms to the patient's body, providing minimum motion and artifact with maximum electrical contact.
