Kendall# 850 series electrodes are high performance adult electrodes ideal for hospital-wide use where a radiolucent feature is needed. The thin foam substrate incorporates an aggressive adhesive, is fluid-resistant, flexible and conforms easily to patient skin. The patented conductive adhesive hydrogel provides additional adhesion, leaves no messy residue and is designed to stay fresh up to 45 days out of the package. There is a lift tab located on one edge to facilitate easy removal from the release liner as well as the patient.
