For investigating the characteristics of metal explosion, the multichannel optic pyrometer was used to measure the radiation intensity of the plasmas produced by metal conductor explosion.
Three-wavelength pyrometer can eliminate the effect of emissivity in the radiation temperature measurement, for example, measuring the surface temperature of a polished metal.
