This RTF1500 series split tube furnace is comprised of the highest-quality components, in order to provide perfectly reliable results each time you use it. It features Silicon carbide (SiC) wire coils. These are placed within Mitsubishi 1500 alumina fiber insulation. A Eurotherm 5x8-segment digital controller offers precise temperature control, while a double-walled steel internal housing minimizes heat loss to the surface. It also has a built-in RS485 digital communications port and a USB adapter. This allows you to connect the furnace to a PC for remote control, monitoring, or to save or print test results.
This tube furnace is compact so it won’t take up a lot of room. It’s lightweight, portable and easy to move and carry, too. Self-tuning PID control will optimize your thermal process and minimize overshoot. The furnace is so intricate, it can perform multiple atmosphere processes in a single cycle. It’s type S thermocouple ensures a long life, while a built-in ammeter and dual voltmeters allow for easy monitoring and troubleshooting. Safety features include overheat and power failure protection. This and all our furnaces, is 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 S 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.
