What is temperature uniformity?

Temperature uniformity is defined as the maximum temperature deviation within the furnace working space. There is a general difference between a furnace cavity and a workspace. The chamber is the total volume available in the furnace.

If an absolute temperature uniformity at a reference temperature or at a defined reference temperature range is required, the furnace must be calibrated appropriately. If, for example, a temperature uniformity of +/? 2C at a set temperature of 200°C is required, it means that measured temperatures may range from a minimum of 198?°C to a maximum of 200°C in the empty work space.

Depending on the type of furnace, insert an insulation rack equal to the size of the working space in the furnace. The framework holds the thermocouple in up to 9-11 defined measurement positions. The measurement of temperature uniformity is performed at the target temperature specified by the user after static conditions have been achieved. If necessary, different target temperatures or defined target operating temperature ranges can also be calibrated.
