ABSTRACT:
A device for measuring the microwave power produced by a microwave oven so as to determine whether the oven is producing its rated or set power, to prevent inadvertent undercooking of food, includes a calorimeter employing tap water as a working medium and a thermometer that can be set initially to read zero for any initial temperature of the working medium. In accordance with the invention, an enclosure containing a quantity of gaseous neon is connected to the calorimeter, and the gaseous neon glows only when radiation is present. The actual irradiation time, which may be less than the set cooking time due to start-up delay, may be accurately determined by timing the duration of the neon glow as observed through the window of the oven.
