This RTF 1200 series rotating split tube furnace is imbued with the highest quality components, in order to provide perfectly reliable results after each use. Sweden’s famous Kanthal spiral wire coils are enclosed within Mitsubishi grade 1500 alumina fiber insulation. This is all encased in a double-walled steel internal housing, which minimizes heat loss. Temperature control is provided by a Eurothermn 5x8-segment digital controller, which can get the tube within +/- 1°C of your target temperature. The unit comes with an RS485 digital communications port and USB adaptor. This allows for remote control or monitoring straight from your PC. You can even save or export your test results.
The split tube design allows for quick and easy access. This furnace is so advanced, multiple atmosphere processes are possible within a single cycle. Its self-tuning PID control optimizes your thermal process with little to no overshoot. Built-in ammeter and dual voltmeters make for easy monitoring and troubleshooting, while its type K thermocouple ensures a long life. It’s lightweight and compact too, making it portable. As for safety features, it comes with overheat and power failure protection. Note that this and all our furnaces are CE compliant.
Compact, portable and lightweight design.
Split furnace chamber for fast and easy tube access.
Standard package includes set of stainless steel vacuum sealing flanges with valves and pressure meter.
Microprocessor based self-tuning PID control provides optimum thermal process with minimal overshoot.
Multiple atmosphere processes in a single cycle are possible (ex: binder burn out in air and parts sintering under rough vacuum or inert gas environment.)
Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting.
Built-in computer interface.
Long life type K thermocouple.
Overheat protection shuts down the furnace if temperature is outside of acceptable range (refer to controller's manual) or when the thermocouple is broken or malfunctions.
Power failure protection resumes furnace operation right after the point of failure when power is reestablished.
Warning! NEVER fill furnace with explosive gases, including Hydrogen, Carbon Monoxide and Methane.
