A probe for an electronic thermometer includes a first elongate, semi-cylindrical probe shaft member having a distal end, a proximal end, first and second edges extending between the proximal and distal ends, an interior surface and an exterior surface. A second elongate, semi-cylindrical probe shaft member has a distal end, a proximal end, first and second edges extending between the proximal and distal ends, an interior surface and an exterior surface. A joint along which the second probe shaft member is attached to the first probe shaft member forms an interior space between the probe shaft members. A probe tip is disposed on the distal ends of the first and second probe shaft members. A temperature sensor is in thermal communication with the probe tip.
