Abstract

PURPOSE:To make it possible to detect and accurately measure an infrared ray without any influence from the fluctuation inemmisivity of a test piece by covering the test piece with a liquid which has its emmisivity made substantially constant for the change in temperature. CONSTITUTION:A liquid such as water having a substantially constant emissivity for the temperature change is poured onto a portion of an aluminum plate 1 or the like to cover that portion with water 4. Then, the setting dial of emissivity of an infrared radiation thermometer 2 is adjusted to the emissivity of the water to detect the emission of the infrared from the water 4 so that the temperature is measured. More specifically, upon the temperature measurement, the emissivity of aluminum exerts no influence, but the emissivity of the water exerts influence so that the temperature can be measured accurately. If the liquid to drop onto the portion to be measured employs a substance having a substantially constant emissivity for the temperature change, similar results can be obtained.
