Temperature uniformity within a furnace can be defined as: a uniform temperature set to operate within a specific tolerance band to create conditions under which a final uniform resulting metallurgy will be accomplished in the treated component.
Your eyes can be a valuable resource in estimating the furnace temperature. Practice observing the color of the furnace in relation to the generated signal/reading on the control instrument.
With practice, you can become very competent at estimating furnace temperature. It is not by the stretch of anyones imagination as being entirely accurate, but it can be simply used as a guide to come within 40-50°F (4.5-10°C) of the setpoint temperature.
I would now like to ask, What does the thermocouple measure? The immediate answer that comes to everyones mind is...
