意に選定することを特徴とする多色放射温度計。 The measurement light emitted from the measurement object is split into multiple measurement lights, and each of the split measurement lights is received by a detector through a corresponding filter and converted into an electrical signal. In a multicolor radiation thermometer that obtains a temperature signal by performing a predetermined calculation using the signal, an approximation formula for the optimum emissivity according to the measurement object is stored in the calculation section, and a switching means is used to calculate the optimum emissivity of the measurement object. A multicolor radiation thermometer characterized in that the approximate expression is arbitrarily selected depending on the substance.
