Large-capacity type. Optimum for various temperature characteristic tests.

A space-saving and large volume type. Various heat treatments and characteristic tests of temperature are possible owing to the accurate temperature control and the large range of temperature. As the input system of the control panel is dialogical, anyone can input easily.

  • Space-saving models for research or production line.
  • A 16-segment program operation is possible.
  • Forced hot air circulation and ventilation by a damper.
  • Safety measures are enriched, including self-diagnosis function and an independent superheating prevention device.
