OTF-1200X-VI-2M-UL is a Six-zone & ultra-long split tube furnace with separated temperature control units and max working temperature of 1200oC. This six-zone furnace can create a step thermal gradient or 60" ( 1500mm ) long constant heating zone by setting all the temperature controllers at the same temperature. The furnace can accept processing tubes with various O.D (1" to 4") at extra cost. Six 30-segment temperature controllers are built in a separate control box which allows PC software control of the furnace from a certain distance. It is an excellent furnace to handle various gases.
