In the use of EPC equipment production is always used to measure the temperature, if the resulting error will also have a great impact, that produces temperature measurement error factors will be those?

I. Steam emission: For high-pressure melting, the overflow of gas in the molten pool or crucible increases or decreases the heat radiation resulting in error.

Hole Barrier: For most instruments any weakening of the signal will result in a drop in temperature indicator values; The dirt on the observation window affects the accuracy of most pyrometer.

Window glass Material: Not all glass has the same transmission performance; some "grey" color and some of the other glass transmittance with the wavelength changes that will make the conventional pyrometer malfunction.

IV. Instrumentation calibration: Through lens aiming requires two optical distances to overlap accurately, which affects the general Pyrometer of all grades.
