Bench-Top Muffle Furnace (1700C, 6"x6"x6", 3.6L) with Temperature Controller - KSL-1700X-A1P

0.0/5 rating (0 votes)


Item Number:KSL-1700X

KSL-1700X-A1P is a CE certified bench-top high temperature muffle furnace. The furnace consists of high quality alumina fiber insulation and 1800 grade MoSi2 heating elements and it's controlled by high precision SCR (Silicon Controlled Rectifier) universal power controller ( updated from 2/26/13 ) and temperature controller with accuracy +/-1°C and 30 segments programmable up to 1700°C or 3092°F. It is an ideal tool for materials annealing and sintering in your research laboratory.


Furnace construction

  • Double shell steel case with cooling fan to keep outside case room temperature
  • High purity alumina fiber insulation for max. energy saving
  • High purity alumian (1765°C) coating inside chamber for longer service life
  • Universal digital power controller whch can be used 50 - 60 Hz worldwid

Temperature Controller

  • PID automatic control via SCR (Silicon Controlled Rectifier) power control with phase angle fired, current limitingresistor.
  • 30 programmable segments for precise control of heating rate, cooling rate and dwell time.
  • Please click here to learn why SCR is more accurate than SSC (Solid state relay).
  • Built-in over temperature alarm and protection allows for operation without attendant.
  • +/- 1 ºC temperature accuracy.
  • RS485 Communication Port.
  • Optional:
    • The furnace may be operated by PC by installing a control module. Please order a MTS-02 control module at extra cost.
    • If you order the PC control module together with the furnace, we will install and test it before shipping. We recommend you to order a computer (laptop) from us to avoid software installation problems. For more information please click here.

Application Note
  • Warning: MoSi2 heating element is used in the high temperature under oxidizing atmosphere. It will form the SiO2 film which can keep the element from being melted. During the oxidizing process, the SiO2 protecting film is formed again when the element continues to be used. The MoSi2 heating element must not be used in the temperature between 400°C and 700°C for a long time, otherwise the element will be cremated under the strong oxidizing function in the low temperature.
