This weighing furnace with integrated precision scale and software, was designed especially for combustion loss determination in the laboratory. The determination of combustion loss is necessary, for instance, when analyzing sludges and household garbage, and is also used in a variety of other processes for the evaluation of results. The difference between the charged total mass and the combustion residue is the combustion loss. During the process, the software included records both the temperature and the weight loss.

Standard Equipment

  • Like muffle furnaces L(T), except:
  • 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
  • Controller B510 (5 programs with each 4 segments)

Additional equipment

Additional Equipment

  • Chimney, chimney with fan or catalytic converter
  • Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
  • Port for thermocouple in the rear wall or in the furnace door
  • Process control and documentation via VCD software package for monitoring, documentation and control
