The oblong, medium-size Ambu BlueSensor T features highly conductive wet gel, offset connector, superior adhesion, and a large measuring area to ensure an optimal signal in stress tests and medium- to long-term applications. Its oblong shape permits the placement of six closely spaced electrodes if the chest is too small to accommo-date our round electrodes. Thanks to the comfortable foam backing, the electrode is easy to use and gentle to the skin.
