| Temperature Control | - Three digital controllers via SCR (Silicon Controlled Rectifier) power control with phase angle fired
- Each controller is 30 programmable segment for precise control of heating, cooling rate and dwells time
- Built-in PID Auto-Tune function with overheating & broken thermocouple protection
- Over-temperature protection and alarm allows for operation without attendant(s)
- +/- 1 ºC temperature accuracy
- Three B-type thermocouples (one for each zone)
- RS485 Communications Port
  |
European Temperature Controllers (optional upgrade)
 | - 1 heating channel
- 1 program of 8 or 24 segment
- Alarm Relay: Form 'A' and Form ‘C’ built-in
- Digital Communications: RS485
- Temperature Accuracy: ± 0.1ºC
- Recipes: Using a PC tool recipes can be created that can be used to change the operating parameters of the 3000 simply by selecting a new recipe via the HMI. This is very useful where multiple products are processed using the same controller but require different parameters to be set.

Warnings
Please click here to learn the installation of a gas regulator. | - The tube furnaces with alumina tube are designed for use under vacuum and low pressure < 0.02 Mpa
- Never use graphite crucible in the alumina tube.
- Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
- The gas flow rate should be limited to < 200 SCCM ( or 200ml/min )
- Vacuum limit definition for all alumina tube furnaces: * Vacuum pressures may only be safely used up to 1500°C
