Vacuum tube furnace is specially used for laboratory, industrial and mining enterprises, scientific research units for elemental analysis and determination and general small steel parts quenching, annealing, tempering and electronic ceramics and other new materials heating. The furnace is composed of multi-channel gas system and vacuum system, can be designed and produced according to user needs (double temperature zone, three temperature zone, multi-temperature zone), can be pre-vacuumed (high vacuum, low vacuum) according to user requirements, through a variety of gases, reliable performance. The control circuit adopts PID program control technology, which has high temperature control precision, small temperature impulse amplitude, reliable performance, simple and easy
Operation and other characteristics.
