NST-1800Cfurnace1 tube furnaces feature a chamber with Mitsubishi (Japan) high quality 1900 grade alumina fiber insulation and the famous Kanthal (Sweden) 1900 grade molybdenum silicide heating elements. A double walled steel internal housing helps minimize heat loss to exterior surface.
Furnace operation is controlled by Shimaden (Japan) 40-segment digital controller with built-in RS485 digital communications port and USB adaptor, allowing the user to connect to a PC for remote control and monitoring of the furnace. You can also save or export test results. All our furnaces are CE compliant.
Features
1 Compact, portable and lightweight design.
2 Standard package includes set of stainless steel vacuum sealing flanges with valves and pressure meter.
3 Dual flanges support ensures better sealing and longer tube life.
4 Microprocessor based self-tuning PID control provides optimum thermal process with minimal overshoot.
5 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.)
6 Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting.
7 Built-in computer interface.
8 Long life type B thermocouple.
Safety
1 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.
2 Power failure protection resumes furnace operation right after the point of failure when power is reestablished.
