Abstract
An apparatus for measuring heating temperature in a high electric field of microwaves comprises a microwave heating chamber, an infrared radiation thermometer disposed outside the microwave heating chamber, a probe formed of a microwave transparent material disposed inside the microwave heating chamber, a fiber cable connecting the probe and the thermometer, and a lens for focusing infrared rays generated from a substance to be heated in the microwave heating chamber and transmitting the focused infrared rays into the fiber cable. By this construction, the focused infrared rays are transmitted outside the microwave heating chamber through the fiber cable so as to measure an infrared radiation temperature by the thermometer. When a purge gas releasing function is added to the probe, the detection of infrared rays can be performed with water vapor and a decomposition gas removed by a purge gas, even when these matters are released from the substance to be heated during microwave heating.
