Description
Features
- Compact, portable and lightweight design.
- Top-open 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.)
- Long life type K thermocouple.
Safety
- 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.
- Limit switch turns off furnace once top is open
Warning! NEVER fill furnace with explosive gases, including Hydrogen, Carbon Monoxide and Methane.
