Oxy-Gon FR-225 Universal Application High Vacuum/Temperature Furnace
Comes with what you see in the pictures. If you don't see it, you probably won't get it.
Specifications are from Oxy-Gon and may vary slightly due to upgrades, options, or revisions this unit may or may not have.
According to the logs of the unit, it was last ran in August, 2020. In 2000 the unit's heating element was upgraded from a tungsten mesh element to a graphite element, 4" dia. x 8" H. We do not have the expertise or facilities to test this unit and are selling it as-is, where-is. The controller cabinet is bent due to it being shipped on it's side. Everything looks fine in the cabinet however.
