<p>Provided is a method for measuring a water content in a compound using a 3-wavelength type infrared water content tester, in which the method uses a reference wavelength combination of a long-wavelength-side reference wavelength "» L " longer than a wavelength "» W " absorbed by water and a short-wavelength-side reference wavelength "» S " shorter than the wavelength "» W " such that the reference wavelength combination makes b in an expression k = aw + b, which is a relational expression between a water content w and an absorbance k of the compound, be regarded as zero within an allowable measurement error of the infrared water content tester, regardless of a mixture proportion of the pre-mixing raw materials.</p> |
