ENDO Disposable ECG Electrode, which are used for various ECG test. It uses an Ag/AgCl sensing element and Hydro-gel for adhesion. These are components for sensitive monitoring. Hydro-gel's main advantage is one of reducing movement artifacts by increasing the bond between the skin and the sensing element. The ECG electrode of ENDO ECG fields. An Ag/AgCl sensing element has the best sensitivities and the solid adhesive hydro-gel has very low impedance.
