Axial temperature subtracted by maximum temperature measured at (a) 200°C and (b) 800°C, and relative temperatures at (c) 200°C and (d) 800°C measured using a thermocouple in two configurations: one in which the thermocouple was placed inside a capillary, and the other where most of the thermocouple was outside the heater with the tip bent into the heater's mouth. |
