Abstract
A radiation thermometer is rationally adjusted during manufacturing processes instead of requiring a user to manually adjust the radiation thermometer each time a temperature is measured, and hence, the radiation thermometer better improves temperature measurement accuracy. The radiation thermometer comprises an infrared ray sensor for detecting an infrared ray from a measurement target; a temperature-sensitive sensor for generating a reference temperature signal; sensor output adjusting means for adjusting an output from the temperature-sensitive sensor and an output from the infrared ray sensor; temperature calculating means for calculating a temperature of the measurement target based on an adjusted temperature-sensitive sensor output and an adjusted infrared ray sensor output which are adjusted by the sensor output adjusting means; and temperature indicating means for indicating the temperature of the measurement target based on a signal from the temperature computing means, and the radiation thermometer is characterized in that the sensor output adjusting means comprises temperature-sensitive sensor absolute value adjusting means (ABS) for adjusting an absolute value of a characteristic of the temperature-sensitive sensor and infrared ray sensor sensitivity adjusting means (KAN) for adjusting a sensitivity of the infrared ray sensor.
