• If using only one zone (center zone), the constant temperature zone is 4.3" (110 mm) long with a temperature discrepancy of +/- 1^oC.

Temperature Accuracy

+/- 1^oC

Heating Elements

Fe-Cr-Al Alloy doped by Mo

Temperature Controller

• Three precision temperature controllers to control three zones separately.
• PID automatic control with 30 programmable segments for precise control of heating rate, cooling rate, and dwell time.
• Built-in overheating & broken thermocouple protection.
• Over temperature protection and alarm allows for operation without attendant(s).
• +/- 1 ºC temperature accuracy.
• RS485 Communications Port.
  
• Optional:  
• The furnace may be operated by PC by installing three control modules. Please order the MTS-02 control modules at an extra cost. 
• The new version of PC module is now compatible with Lab View 05/08/2014
• 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 computer laptop from us to avoid software installation problems. For more information please click here.

• 80 mm O.D x 72 mm ID. x 1400 mm fused quartz tube included.
• Vacuum flanges with valves and pressure gauges are included. 
• The thermal block must be placed inside the tube as in the drawing below

• Corrosion-proof Capacitance Diaphragm Gauge with ceramic coated sensor head specially designed for vacuum measurements with the presence of corrosive gases.
• Gauge is installed on the vacuum flange (right side) of the tube furnace and provides a wide measure range (10^^-5 ~ 1000 torr).
• Optional:   click the pic-below- right to order the Constant temperature control module.
  
  

• Slide for transferring sample (manually operated) is available as an option at $1900 extra cost (please refer to pictures below).

•        

• Two stainless steel flanges with both vacuum gauge and valves included.
• Min. vacuum pressure achieved by the mechanical pump is 5.5 m-torr. ( 5.5x10^^-3 torr). The pressure can reach 10^^-5 torr by using a mechanical + molecular pump.
• The leaking rate is < 5 m-torr / min. and stable vacuum pressure after 24 hours is < 2 torr.
• Click the picture below to get a details chart and data measured by CE certified vacuum meter:        

(For a whole 24 hours curve display, the time segment through 08:00:00~21:10:00 in X axis is passed over in the chart, therefore, steep variety in there)

Oxygen Monitoring

An Oxygen Sensor can be used to monitor the oxygen level of gas(es) used in CVD systems for preventing or reducing oxidation. Please click the picture below to learn more:
         

Vacuum Pump

• 120 L/m Rotary Vane Vacuum Pump is included with max. vacuum pressure of 10^^-2torr. Stainless steel hose tube is included for connecting to the tube furnace.
  
• Option: For precise control of the vacuum pressure, we recommend you choose our turn-key solution EQ-VPC-MV. This is a vacuum pressure regulating system with a motorized valve and gauge. It controls pressure range from 10^-6 torr ~ 760 torr.

• Three gas flow meters (4% accuracy FS) are installed inside the mobile case to enable monitoring of gas flowing rates (three different kinds of gases in total).
•  Compact direct read flow meter, 10-100 cc/min.
•  Compact direct read flow meter, 16-160 cc/min.
•  Compact direct read flow meter, 25-250 cc/min.
• Four pressure meters are installed inside the mobile cart which is able to monitor three types of flowing gas pressure as well as the pressure of the mixing tank.
