Item Number: KSL-1700X-A4-DC


Upgrade to Eurotherm Temp. Controller
KSL-1700X-A4-DC is upgraded model of KSL-1700X-A4 furnace. This model equips with two sets of MET certified temperature controllers and two B type thermocouples, the primary controller and the monitoring controller to ensure the safety. The gas route is built to allow inert gas into the chamber and the safety door lock prevents furnace door from opening by accident during operation. The furnace adopts high-quality alumina fiber bricks insulation and MoSi2 heating elements which achieve a temperature capacity of 1700°C in the 12"x12"x16" chamber. This model of box furnace is ideal for R&D, laboratory and also industrial use.

Furnace Structure

  • Double shell steel case with cooling fan to keep outside case at lower temperature
