These electrodes can be used in electrocardiography for patients from newborns babies to adults.
The following electrodes are available, with a range of shapes, surface materials, and hook terminals. The gel is kind to the skin, non-irritant and stays moist. - Full-surface gel monitoring electrodes (for both children and adults) - Monitoring electrodes which can be penetrated by X-ray (large and small sizes, with adhesion frame) - Monitoring electrodes with adhesion frames (foam or cloth, in a range of shapes) - Electrodes for examinations (resting ECG electrodes)

Characteristics
- Impedance across electrode pair: not more than 20 kΩ - Voltage across electrode pair: within ±100 mV
Features
The full-surface gel adheres gently to the skin. A cloth material has been used for good air permeability, making the electrodes safe for newborn babies.
