Temperature Control
|
- Three EPC 3004 Eurotherm temperature controller with 28 programmable segments for precise control of heating, cooling, and dwelling rate.
- Built-in overheating & broken thermocouple protection.
- European Temperature controller, with +/- 0.1 ºC temperature accuracy.
- Three B type thermocouples (one for each zone).
|
| Cooling Fans |
- One speed adjustable cooling fans are installed at the bottom exit of the furnace
|
| Furnace Travel Distance & Speed |
- As the furnace heater moves upward, the crucible is moving toward the bottom exit of the furnace where the lower temperature is seen.
- The maximum travel distance of the furnace heater is 200 mm.
- Travel speed: 0.03-3 mm/hr
|
| Vacuum Pump (Not included)
|
- 10E-2 torr via dual-stage mechanical vacuum pump (bottom right picture)
- 10E-5 torr via Turbopump (bottom left picture)
- The vacuum pump is optional. Please click here to choose a vacuum pump.
- For oxygen-sensitive material, suggest using recirculating gas purification system ( < 1 ppm) to replace turbopump (Pic. 3 - 4)
 Pic. 1  Pic. 2  Pic. 3  Pic. 4
