Elektrotlar iki \u00e7e\u015fittir. \u0130\u011fne elektrotlar ve y\u00fczeysel elektrotlar. \u0130\u011fne elektrodlar\u0131n i\u00e7inde \u00e7evre ile izole edilmi\u015f ince bir tel vard\u0131r. Bu telin sadece u\u00e7 k\u0131sm\u0131 a\u00e7\u0131kt\u0131r. Aktif elektrod olarak \u00e7al\u0131\u015fan k\u0131s\u0131m sadece bu a\u00e7\u0131kta kalan u\u00e7 k\u0131s\u0131md\u0131r ve alan\u0131 1 mm2\u2019yi ge\u00e7mez. Baz\u0131lar\u0131n\u0131n i\u00e7inde iki tel bulunabilir. Y\u00fczeyel elektrodlar ise, \u00e7o\u011funlukla 70 mm2\u2019nin alt\u0131nda bir \u00e7ift kalay levhad\u0131r. Deri, alkol-eter kar\u0131\u015f\u0131m\u0131yla temizlendikten sonra, y\u00fczeysel elektrotlar, elektrolitik bir macun arac\u0131l\u0131\u011f\u0131 ile deriye yap\u0131\u015ft\u0131r\u0131l\u0131r.
