- 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
