XL-1 muffle furnace has reasonable design, simple structure and convenient operation. Compared with similar products in China, its advantages are: easy maintenance, good thermal insulation effect, fast heating speed, and movable furnace core assembly, that is, the furnace core can be removed from the back of the furnace. Withdraw from the board, the electric wire can be replaced without moving the insulation layer. A controllable chimney is installed behind the furnace to prevent contamination in the furnace and to ensure the accuracy of the sample. Meet the national standard (GB212-77) standard requirements.
The muffle furnace is designed according to the requirements of national standards ( GB212-2001), with simple structure, convenient operation, easy maintenance, good thermal insulation effect and fast heating speed.
The lightweight insulation brick is selected as the insulation material, which has high strength, good insulation performance and convenient maintenance.
There is a controllable chimney that can be closed and closed at the rear of the furnace body, which can be adjusted according to the requirements of use.
Using single chip microcomputer control, one experiment can measure the ash or volatile content of a batch of coal samples.
With optional module for temperature and time control, it is convenient for users to perform inspection burning, or to control temperature and time according to user's wishes.
There are two types of control temperature: digital display controller and program controller.
