Abstract In this paper, a non-dimensional emissivity model with universality is established. For the tri-wavelength method of temperature measurement, based on the non-dimensional emissivity, the applicable measurement condition and theoretical analysis of wavelength choice are mainly introduced. In the discussion of theoretical analysis of wavelength choice, by optimizing the analysis of measurement method and the concept of isothermal line induced by the measurement coordinates, two kinds of ideal choice rules of measurement wavelength are put forward, which will be necessary to the technology application of this tri-wavelength method. Meanwhile the optimizing idea is also applicable to multi-wavelength method of temperature measurement.
