High-Performance Vacuum Muffle Furnace for Material Process Testing in Nitrogen or Vacuum Environments

HWF80-04N Type Dehydrogenation Furnace

The HWF80-04N type dehydrogenation furnace is suitable for medium-temperature heat treatment of electronic products. It is primarily used for sintering processes of related materials under nitrogen or vacuum environments. The furnace is fully equipped with a real-time computer monitoring system, making it particularly suitable for material process testing requirements in research institutes.
