Temperature Uniformity

Type B Standard Thermocouple Furnace: the hottest point in the furnace must not deviate more than 20 mm from the furnace center. Within ±20 mm of the hottest point, the temperature gradient must be ≤ 0.5 °C/10 mm.
Type B Working Thermocouple Furnace: the hottest point in the furnace must not deviate more than 20 mm from the geometric center. Within ±20 mm of the hottest point, the temperature field must be uniform with a gradient ≤ 0.5 °C/10 mm.
