Technical Data

The universal microwave laboratory furnace, which is placed in a shaply norm housing, characterizes itself through special design of microwave applicators and coupling type of microwaves. Consequently it prevail favourable working conditions for the three 900 W microwave generators f.ex. minimal reflection of microwave power in direction to generator. The power is stepless adjustable over potentiometer from 15-100%.

Further characteristics are:

  • 3 air cooled 0,9 kW magnetrons with frequency 2,45 GHz
  • Homogenous power distribution in  the multimode chamber
  • Increase of homogenity of temperature distribution in the material through a  Al2O3- or Teflon-rotary disc with drive motor and 100 mm diameter
  • External control of power (0 to 10 V)
  • Extensive safety devices
  • Viewing window in the door
  • Effective microwave damping component which prevents escaping of stray radiation and  leakage radiation (≤ 5 mW/cm2).
