Thermal temperature measurements of a plasma torch by
alexandrite effect spectropyrometer and enthalpy probe
The thermal temperature of a low power rod-type plasma torch is measured by
the alexandrite effect spectropyrometer and an enthalpy probe. The plasma torch
is operated with Ar gas at 8 KW power. Figure 1 shows the temperature
measurement of the plasma torch by the spectropyrometer. The measured thermal
temperature of the plasma torch is 2511 K.

torch by the alexandrite effect spectropyrometer.
The enthalpy Probe System from Tekna is a complex instrument for high accurate
thermal temperature measurement of plasma. Figure 2 shows the temperature
measurement of the plasma torch by the enthalpy probe. The measured
temperature by the enthalpy is 2511 K, which is the same as that measured by the spectropyrometer.
