laboratory furnace

muffle furnace


  • the laboratory furnace are used for a large number of high thermperature treatments: burnring, degassing , pre-heating,hardening,tempering, annealing of metals,stress relief,stabilization,tests… in many branches of industry. temperature range: up to 1200℃, electrionic pid controller,ramping to set up temperature temperature fluctuation: less than±1℃.


  • from compact design, control panels are at the bottom part of the furnaces to minimize their size.
  • the inner casing is made of ceramic fiber.
  • the outer casing is made of stainless steel.
  • the optimized heat insulation is made of ceramic fiber totally as bestos-free, ensuring efficient operation, low external temperature and excellent thermal stability.
  • the door opening manually downwards
  • heating
  • the heater surround the chamber to ensure homogenous heating.
  • no-wear switching (solid state relay) is used for activating and deactivating the heating elements. the micro switch at door edge cut off heating.
  • exhaust air, fresh air supply:
  • a 20mm diameter exhaust vent is provided at the rear of the furnaces.
  • temperature control and safety:
  • temperature sensor is s thermocouple. the temperature is controlled by a precise microprocessor-based controller that provides a high accuracy and prevents the set temperature from being exceeded. the alarm integrated inside the controller has an adjustable deviation limit, giving a class 3.1 protection.
  • the controller digitally displays the set and actual values of temperature. anad incorporates a heater indicator lamp. the control panel houses a on/off switch and a fault indicator lamp which lights when the safety device comes into operation.230 volts plug at the rear.
  • quality control:
  • every furnaces is carefully checked at the end of the producton process .a check report can be supplied on simple rquest.

    standard dimension width: 250mm x depth 340mm x high 170mm
