GSL-1500X-50HG tube furnace is designed for processing material under hydrogen gas up to 1500 °C safely. The 50 mm OD processing tube is made of pure alumina, and one hydrogen gas detectoe is included which will shutdown hydrogen gas via a built in solenoid valve immediately once detecting hydrogen gas leaking. Also the furnace can be used for all kind of inert gases and oxygen gas. Precision temperature controller is 30 segment programmable.
Specifications

Temperature controller
•PID automatic control via SCR (Silicon Controlled Rectifier) power control, e.g. current limiting phase angle fired the resistor with 51 steps programmable. •Self-tuning and built in protection from over-heated and broken thermal couple. Please click here to learn why SCR is more accurate than SSR (Solid State Relay) •Optional : PC control interface & Software is available at extrat cost, click picture below to see detail specs and order separately
Temperature Accuracy
+/ - 1 °C
Flanges and Gas Inlet
•One pair stainless steel vacuum flange are installed on two ends of tube which allow high vacuum upto 10E-5 torr and 5 PSI positive pressure. •One solenoid valve is installed on left of flange for Hydrogen gas inlet. It connects with hydrogen detector. Once hydrogen gas leak is detected ( 10% below hydrogen explode point ), gas inlet valve will be shutdown immediately •One pressure gauge is installed on the end of gas inlet. Hydrogen gas pressure must be controlled under 5 PSI, which can be adjust by a stainless steel needle valve.

Gas-outlet Flowmeeter & Hydrogen Detector
•One 1000 ml/min floating meter is installed on gas-oulet end for adjusting gas flow rate •1/4" dia stainless steel tube is installed for burning hydrogen gas during gas flowing •One long lighter is included in the standard package for igniting hydrogen gas manually. •One 3M hudrogen detector and power supply are included (click underlined for detail specification.) •Solenoid Value automaticly shuts down the gas inlet in case of system failure
One year limited warranty for electrical and mechanical parts
Compliance
•CE Certified •UL / MET / CSA Certification is available upon request, additional charges will apply •Temperature controller is MET and CE Certified •Transformer is UL Certified
Warning
•The tube furnaces with alumina tube are designed for using under vacuum and low pressure < 0.12 atm (absolute pressure) •In order to avoid thermoshocking the tube, please limite the gas flow rate < 200SCCM
