Muffle Furnace is used to heat the air in the chamber by heating the Nichrome (nickel-chromium)
wires which are generally referred to as electrically operated heating
elements. The Control of Muffle Furnace temperature majorly depends on the
efficiency of electronic controller unit and best results can only be
obtained from PID controlled units. The laboratory muffle furnaces do not
have a cooling system, however they do have ventilation windows.
