Features:-

 

  • The Furnace Material Is Vacuum-Formed Alumina Ceramic Fiber Material And Does Not Drop Powder In High Temperature; Heat Capacity Is Small, Energy Saving Above 50%.

 

  • The Heating Element Is Made Of High-Quality Kanthal “A-1” Grade as Heating Element, Which Can Bear Low Load, Stable And Long Service Life; The Kanthal APM Grade Is Evenly Arranged On Both Sides Of The Furnace, And The Temperature Field Uniformity Is Good.

 

  • The Heating Rate Is Fast, From Room Temperature To 1150 Degrees, Generally Takes 120 Minutes.

 

  • High Precision of Temperature Accuracy ±1°C.

 

  • PID automatic control via SSR power control with phase angle fired, current limiting resistor.
  • 1 programmable x 16 segments for precise control of heating rate, cooling rate and dwell time.
  • Built in PID Auto-Tune function with overheating & broken thermocouple broken protection for this Muffle Furnace 1400 type.
  • Over temperature protection and alarm allows for operation without attendant

                                         

  • Electronic Components Are Used Such As Autonics / Schneider / L&T Brand, its Safe And Reliable.

 

  • The Machine Will Send Out An Alarm Signal To The Over-Temperature During The Working Process, And Automatically Complete The Protection Action.

 

  • When The Instrument Program Is Set, Just Press The Run Button And The Next Work Will Be Completed Automatically.

 

Product Overview:-

 

HE-MF 1200℃ Series Products Are Mainly For The Daily Application Development of The Laboratory, High-Quality Furnace Materials And Stable Temperature Control System To Ensure The Reliability of The Experiment; The Product Uses Light weight ceramic Fiber wool insulation (instead of Brick insulation) As The Furnace Material, And The Kanthal “A-1” Is Used For Heating Element, And The Temperature Controller Uses Microprocessor PID Control Module To Achieve Precise Temperature Control And Constant Temperature Requirements
