Abstract
Abstract For use in connection with oral clinical thermometers and average reading industrial thermometers, a plurality of branches on a single probe connected to yield a temperature reading which is the average of the temperatures sensed at each branch. For oral use, the spaced distance between two branches is substantially the same as the distance between the pockets on opposite sides of the fraenum of the tongue to prevent lateral movement of the probe and resulting erroneous temperature measurement.
