Specific Introduction:
    KJ1200X-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.
Furnace structure · Double layer steel case with two cooling fan, which ensures low surface temperature.
· Energy saving high purity fibrous alumina insulation.
·The surface of the inner furnace is coated with a high-temperature alumina coating imported from the United States, which can improve the heating efficiency of the equipment and also extend the service life of the furnace
· One flange is supported by sliding rail to make sample loading /unloading easy, and another seal flange is installed with a digital vacuum gauge.
One Double Steps Rotary Vane High Speed Vacuum Pump (240 L/m) with Oil is included. 
 Voltage & Power · AC 208-240V Single Phase, 50/60 Hz  (40A breaker required).
· Powder cord is included without plug.
7 KW Max.
 Max. Temperature 1200 oC
