Attention of 1800 ℃ box type muffle furnace
The heating rate is measured when the temperature is set to 100 ° C below the maximum temperature and running without load.
The insulation power is measured under continuous working conditions.
The external dimensions are measured when the furnace door is closed, including the dimensions of the chimney.
The volume of the uniform temperature zone is smaller than the total volume of the furnace.
