The specular reflection pyrometer has the advantages of decrease the influence of surface emissivity on temperature measurement, but the short continuous working duration limits its application.
镜面反射式高温计具有能减少被测表面发射率影响的优点，但它的连续工作时间短，限制了应用。

The pyrometer gives a more accurate reading than either the surface thermometer or the crayon discussed previously.
与前面介绍的表面温度计或热敏蜡笔相比，接触式高温计的测量结果更精确。

Three-wavelength pyrometer can eliminate the effect of emissivity in the radiation temperature measurement, for example, measuring the surface temperature of a polished metal.
