1100C Hydrogen Gas Tube Furnace with 60mm/80mm Quartz Tube with H2 Detector System - OTF-1200X-II-H2

• 220 VAC, single phase, 50/60 Hz. 
• Maximum power: 3 kW (20A breaker required)
• A power cord is included without the plug

• 100~1100°C (Continuous)
• 1200°C (<1 hour) 

• ? 20 /min

• One 60mm/80mm high-quality quartz tube.
• Two fibrous ceramic tube blocks are included for blocking heat radiation from the tube chamber. (Two Ceramic blocks must be fully inserted into the furnace chamber before heating)
• Quartz blocks (optional) are ideal for cleaner and higher vacuum efficiency             
•                                      
• Two heating zones: 8” (200 mm) heating length for each zone, 16" (400 mm) total heating area. 
• Double-layer steel casing with air cooling.
• The hydrogen gas furnace must be placed under a fume hood which is not included. 
• Please click to view the spec of MTI EQ-FH-36 fume hood

• Built-in PID auto-tune function with overheating & broken thermocouple protection
• Over-temperature protection and alarm allows for operation without attendant(s)
• Precise temperature control with less than 1 temperature fluctuation during the dwelling.
• Optional:  
• The furnace may be remotely controlled by a PC by installing a communication module in the controller. Please order an MTS-02 control module at an extra cost
• If you order the PC control module together with the furnace, we will install and test it before shipping. We recommend you to order a software-ready laptop from us 
•                         

• 150mm (+/-1°C) heating area with the best temperature uniformity for each heating zone. 
• A longer area of temperature uniformity (~ 250mm) can be created by setting both zones at the same temperature

Flanges & Fittings
(Flange size will be matched with the tube size. Please select in the options bar)

• Flanges with 1/4” tube fittings and mechanical valves are included on both sides.
• Flange fixtures and tube covers are installed to provide additional safety protection in case of hydrogen hazards. It is easy to open one side of the flange for quick sample loading
• Flange with an additional 1/4" thermocouple feedthrough is available at an extra cost for in-situ temperature calibration and measurements.
• Flange with KF25 port is also available at an extra cost for a quick connection with a vacuum pump.
• Water-cooled flanges at an extra cost are required if thermal blocks are not inserted. 

• The tube furnace comes with a pressure gauge and 0 - 1000 ml/min floating flow meter to precisely control the overall pressure and flow rate in the quartz tube. 
• Two separated gas delivery lines for hydrogen and inert gases.
• The inert gas line comes with a mechanical needle valve.
• The hydrogen line comes with a mechanical needle valve and a solenoid valve controlled by the hydrogen gas detector. 

• One Honeywell UL Approved Sensepoint Gas Detector is integrated into the system.
• Working Temperature Range: 40ºF to +149ºF (-40ºC to +65ºC)
• Alarm Set Point at 10% (10% LEL). The hydrogen gas delivery line and heating elements will be shut down automatically once the alarm is activated. 

• 1/4" O.D. stainless steel tube on the right side is installed as a hydrogen torch with a manual light to safely burn out the hydrogen exhaust. 

• 590 mm(L) x 380 mm(W) x 520 mm(H)

• ~50 kg

• 200 lbs

• One year limited warranty with lifetime support. 
• The quartz tube as a consumable part is not covered by warranty. 
• Attention: A free course of safety operation training at the MTI field is required to purchase this furnace. A customer's side training is also available upon request at extra cost. If the users believe that they have sufficient experience and knowledge to handle the furnace in a dangerous situation or emergency, a liability release agreement must be signed at the purchase. MTI Corporation is not responsible for any damages caused by misuse without safety operation training. Any damages caused by the corrosive and acidic gases are not under the coverage of the MTI One Year Limited Warranty.

• CE Certified

• Tube furnaces with alumina tubes are designed for use under vacuum < 0.12 atm (absolute pressure) and low  positive pressure 
• The flow rate of  gases should be < 200 SCCM (or 200 ml/min) for reducing thermal shocks to the tube
• Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
  
• Please note that the regulator for hydrogen gas is different from that for inert gas. 
•  Quartz tubes may only be safely used up to 1000° under vacuum conditions.
