  • Max. Constant temperature zone 35"  ( 875 mm ) if 7 zone heated  at same temperature ( within +/- 2  °C)
Temperature Controllers

  • One touch screen digital temperature controller built in a separated unit, which can control seven heating zones independently
  • Each channel is PID automatic controlled  and saves 10 programs and each program has max. 30 segments
  • Built in overheating & broken thermocouple protection.
  • +/- 1 ºC temperature accuracy.
  • Seven K type thermocouples (one for each zone).
  • RS485 Communications Port built in. and software included, 
  • The furnace may be operated by PC ( please order PC separately ).
  • You may add a multi-channel gas delivery system under bottom table  for CVD or atmosphere control applications ( click PIC below-left to order )
  • You may consider a pressure control unit to keep constant pressure ( click picture below right to order )

Shipping Weight & Size
  • The tube furnaces with quartz/mullite tube are designed for using under vacuum and low pressure < 0.2 bar / 3 psi / 0.02 MPa
  • Attention: A two stage pressure regulator must be installed on gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
  • * Vacuum pressures may only be safely used up to 1000°C  
  • The flow rate for gases should be limited to<200 SCCM (or 200ml/min) for reducing thermal shocks to the tube
