Maximum operating temperature of 1200 DegC
  Tube diameters from 19.5 - 150mm id
  An integral worktube is not fitted and therefore a worktube must be ordered separately
  Existing customer worktubes can be used - however, the outer diameter & length must be specified at the time of ordering
  Seven heated lengths from 300 - 1200mm
  Heating is provided by resistance wire heating elements, semi-embedded in rigidised vacuum formed low thermal mass insulation modules, which when used together with a ceramic worktube ensure excellent thermal uniformity
  Rapid heat up to operating temperature
  Optional removable tube adapters allow rapid changes for different size worktubes
  Can be adapted to allow a non-oxidising atmosphere or vacuum, if required, by fitting an additional worktube and end seals
  Applications in materials research include testing of novel materials under strict temperature & various atmosphere conditions
  Applications in the electronics industry include testing electronic components and semiconductor materials under inert atmospheres or vacuum
  Applications in instrumentation include testing of temperature sensors such as thermocouples and PT100's, which may require enhanced thermal uniformity
  For enhanced thermal uniformity, three zone models are available
