CTF models
Maximum operating temperature of 1200°C
Tube diameters of 65, 75 and 100mm
Heated lengths of 550, 700 & 900mm
These models utilise a resistance wire heating element wound around a ceramic worktube, forming an integral part of the heating element to ensure excellent thermal uniformity
Rapid heat up to operating temperature
Can be adapted to allow a non-oxidising atmosphere or vacuum, by fitting an additional worktube and end seals
The thermocouple is located in a protected position between the outside of the worktube and heating element, allowing the full worktube diameter to be used
Normally built on the horizontal base pictured left, this furnace range can optionally be mounted vertically with a separate control box
Applications in materials research include testing of novel materials under strict temperature and varying 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
