This furnace offers improved temperature and reduced response times to meet the requirements of ISO 562.
  Fast heating: Powerful open spiral elements are supported in lightweight insulation, providing fast heating – typically 20 minutes to 900 degC.
  Use of a sophisticated algorithm ensures fast recovery of temperature after loading the samples - less than 4 minutes to return to 900 degC +10 degC.
  Calibration ports are provided which permit the insertion of unsheathed probe thermocouples, from the back of the chamber, without risking touching live electrical connections.
  The probe thermocouple can be positioned under each crucible in turn.
  A chimney or flue is provided at the back of the chamber.
  Insulation: Hardwearing refractory brick is used around the doorway and a SiC floor provides abrasion resistance : lightweight ceramic fibre is used in other areas to ensure energy efficient fast heating and cooling, together with low heat loss into the room.
  Door action: A parallel upward action keeps the hot face insulation away from the operator during loading and unloading : when the door is opened, a positive action safety switch automatically isolates the heating elements from the supply to protect the operator from accidental contact with a live heating element.
  Power switching : solid state thyristor based zero voltage switching and rapid cycle time give smooth and reliable control with minimal electromagnetic emissions.
  Service is aided by diagnostic warning lights, a removable front instrument panel and easy access to the heating elements and thermocouple.
  Cool & safe outer case temperatures are achieved by natural convection moving air silently and reliably through cooling passages.
