Transported by LTL Freight (Truck)

Product Options

UL/CSA Certification:


Upgrade to Eurotherm Temp. Controller

KSL-1700X-A1-HB4 is a hybrid box furnace, which can insert four 40 mm alumina tube as multi vacuum tube furnace. The furnace is controlled by the precision temperature controller with +/-1 °C accuracy and 30 programmable segments  up to 1700 °C (3092 °F). It is a cost effective tool for exploring material properties at same temperature but different atmosphere .


Furnace construction

  • Double layer steel structure with air cooling fan to keep the case's temperature below 60°C
  • High purity alumina fiber insulation for max. energy saving
  • The furnace can be used as both muffle furnace and multi tube furnace.
  • Four 40 mm OD alumina tube with vacuum sealed flange are included 
  • Thermal insluting rods are included for blocking the hole for tubes when use as muffle furnace.
Temperature Controller
  • FA-YD518P-AG temperature controller is included.
  • Proportional–integral–derivative control (PID control) and auto-tune function
  • 30 segments programmed with ramping, cooling and dwelling steps
  • Built-in over-temperature alarm and thermocouple failure alarm
  • +/- 1 ºC temperature control accuracy
  • Default DB9 PC communication port
  • MET Certified
Temperature controller (optional)
  • MTS02-Y Temperature control software kit (for YD518P series controllers) + 15" laptop package  is available at the options bar. Click for the detail information about the MTS02-Y software kit. 
  • You may upgrade the temperature controller to the  which is fully compatible with LabVIEW. This package includes a Eurotherm 3504 programmer, a communication cable (RS485 - USB) and a software CD. Click the pic below to view the full spec of Eurotherm 3504 temperature controller.    
Laptop, software & WiFi Control(Optional)

Application Notes
  • Warning: MoSiheating element is used in the high temperature under the 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 long time, otherwise, the element will be cremated under the strong oxidizing function in the low temperature.
