3M 2237 Red Dot Monitoring Electrode, 1.75" Diameter

These electrodes are well suited for applications where fluids are present, due to the foam polyehtylene backing that is fluid-resistant. Because they don't absorb liquids, which could reduce the electrode's ability to adhere well to the patient's skin. Patented solid gel conforms to the skin quickly allowing high quality, uninterrupted traces. The gel's low chloride content minimizes skin irritation for increased patient comfort. Use of built-in abrader disc improves trace quality for better results. Provides good performance for up to 30 days out of the bag. Foam backing is comfortable for patients, and is easy to handle and use. Lift tab makes electrode removal easy.
