Abstract
A food temperature-sensing probe assembly for monitoring the internal temperature of food while it is being cooked in a microwave oven includes a disc-like reflector mounted at a fixed position on the probe housing a predetermined distance from the tip of the probe housing. The probe housing is adapted to be driven into the food so that the reflector is adjacent to, but spaced from, the food. The reflector serves to prevent overcooking of the food in a region immediately adjacent the probe. An indicator on the probe housing shows the minimum recommended insertion depth of the probe into the food, and therefore the maximum reflector-to-food spacing, for effective shielding. The reflector and the handle may be formed as a single assembly held together by insert molding.
