For use in monitoring the temperature of a heart during open heart surgery involving a cardioplegia system, the invention comprises a housing and mount for a temperature responsive liquid crystal chip or small panel which provides a visual temperature reading in various selected ranges. The housing includes an insulating shell enclosing a heat sink sheet associated with a highly conductive mounting pin which penetrates the wall of the heart and conducts the heart temperature to the heat sink underlying the liquid crystal panel.
