1200‚°C, 1500‚°C, 1600‚°C, 1700‚°C & 1800‚°C Three zone tube furnaces (TZF/GHC/GVC)

Horizontal and vertical three zone tube furnaces

1200°C Three Zone tube (TZF)

• Maximum operating temperature 1200°C
• Tube diameters range from 38 - 100mm
• Heated lengths from 400 - 900mm
• These models utilise three resistance wire heating elements wound around the integral ceramic worktube
• Three control systems balance the power to the heating elements to ensure excellent thermal uniformity
• The thermocouples are 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 Instrumentation include testing of temperature sensors such as thermocouples and PT100's, which require enhanced axial thermal uniformity
• Applications in Materials Research include testing of novel materials under strict temperature conditions
• Applications in the Electronics Industry include testing electronic components and semiconductor materials
• This range can be supplied with three equal heated lengths, for special applications
