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

Technical Specifications

Application Notes

• Don't fill any explosive gasses such as Hydrogen or Methane into the furnace tube without necessary safety controls and supervision
• 1700C tube furnaces with alumina tube are designed for use under vacuum and low pressure; 0.2 bars / 3 psi / 0.02 MPa
• To minimize the cracking rate of the ceramic tubes, please change the position (mark four points on the tube) each batch
• 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
