ECG Strippers 4 Lead incorporate wet gel foam electrodes with a one piece, pre-attached leadwire system to minimize the patient set-up time and to prevent leadwire tangling. Closed cell foam electrodes keeps fluids from penetrating, while the wet gel formula provides quick ECG signal retention. A pull tab makes it easy to apply and remove electrode. They feature a "strippable" leadwire construction so each leadwire can be "stripped" to desired length.
