These high-temperature furnaces were specially developed to determine combustion loss during annealing and for thermogravimetric analysis (TGA) in the lab. The complete system consists of the high-temperature furnace for 1600 °C or 1750 °C, a table frame, precision scale with feedthroughs into the furnace and powerful software for recording both the temperature curve and the weight loss over time.

Standard Equipment

  • Defined application within the constraints of the operating instructions
  • Tmax 1600 °C or 1750 °C
  • High-quality molybdenum disilicide heating elements
  • Dual shell housing made of textured stainless steel sheets with additional fan cooling for low surface temperature
  • Adjustable air inlet
  • Exhaust air opening in the roof
  • Type B thermocouple
  • Delivery includes base, ceramic plunger with base plate in the furnace lining, precision scale and software package
  • 4 scales available for different maximum weights and scaling ranges
  • Process control and documentation for temperature and combustion loss via VCD software package for monitoring, documentation and control
