OTF-1200X-2 is cover splitable Tube furnace with Fe-Cr-Al alloy heating element, which can achieve faster heating and cooling rate. The furnace is installed with 50 mm diameter quartz tube with a pair of smart stainless steel vacuum sealing flange, 1/4" in diameter vacuum sealing assembly will connect with 1/4" rubberhose, which allow to heat sample in vacuum or flowing gas. The temperature of OTF-1200X-2 tubing furnace is controlled by high precision SCR power controller with accuracy +/-1 oC and 51 segments programmable up to 1200oC .Specifications:
