ABSTRACT:
To provide a temperature measuring apparatus making it possible to automatically calculate a correction multiplier by assuming the data measured by a contact-type thermometer as a true value and always accurately measure temperature by the noncontact method in accordance with the correction multiplier. The temperature measuring apparatus comprises noncontact- and contact-type thermometers for measuring the temperature of a temperature measurement object, arithmetic means for calculating a correction multiplier for correcting an error of data measured by the noncontact-type thermometer in accordance with the data measured by the noncontact-type thermometer and a value measured by the contact-type thermometer and moreover calculating a correction value by correcting the data measured by the noncontact-type thermometer in accordance with the correction multiplier, and display means for displaying the measured value and the correction value.
