Product Details
Product Overview for Quartz Tube Furnace
1200C series multi-zone tube furnace PT D120/900/12/3 is a long,
and split-able three-zone tube furnaces with tubes up to 100mm O.D
capable of quickly heating up to 1200°C. The multiple zones also
enable the user to create different thermal gradients by varying
the temperature of the three zones. The furnace includes one fused
quartz tube, one pair of vacuum sealing flanges with a pressure
gauge & a ball valve for immediate use. Three-30 segments of
temperature controllers are installed with a N-type thermalcouple.
Microprocessor-based self-tuning PID control provides excellent
temperature control without overshooting along with an accuracy of
+/- 1 °C. It is an excellent furnace for annealing, diffusing, and
sintering samples under various gas atmospheres

Safety Measures
- Built-in ammeter and dual voltmeters for easy monitoring and
troubleshooting.
- Overheat protection shuts down the tube furnace if temperature is
outside of acceptable range (refer to controller's manual) or when
the thermocouple is broken or malfunctions
- Power failure protection resumes furnace operation right after the
point of failure when power is reestablished
- Microprocessor based self-tuning PID control provides optimum
thermal process with minimal overshoot

Application Notes
- Don't fill any explosive gasses such as Hydrogen or Methane into
the furnace tube without necessary safety controls and supervision
- Laboratory tube furnaces with quartz tube are designed for use
under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa
- Small cracks may appear on the surface of the refractory ceramics
over extended use. This is a normal occurrence and the cracks may
be repaired with alumina coating
