OTF1200X-5-III-SF is a CE certified split 5" (O.D) three-zone tube furnace, which can achieve faster heating up to 1200oC and create a different thermal gradient by adjust three zone temperature. The furnace includes all accessories for immediate use. It is an excellent furnace for annealing, diffusing and sintering sample in various atmospheres.
- One 5" O.D x 1400mm L fused quartz tube and one pair of vacuum sealing flanges with pressure gauge；
- Three 30 segments temperature controllers are installed with K type thermal couple. Microprocessor-based self-tuning PID control provides excellent control without overshootingａnd +/- 1 oC accuracy；
- 800mm long sliding rail is installed with one end flange to make loading & unload sample at easy；
- Two carts are included to support furnace and sliding rail；
- Three flowmeters (range: 0-100 ml/min, 0-160 ml/min, 0-250 ml/min) are installed in one of cart, which allow to use three types of gas during heat treatment；
- One mechanical pump with KF25 adaptor and SS pipe are included with furnace；
- One digital vacuum gauge is installed on the flange for easy vacuum pressure reading upto10 -4 torr；
