Vacuum and Atmosphere Controlled Tube Furnace


Make and Model:

Carbolite HZS 12/900



The HZS (three zone) furnace uses free radiating wire elements embedded within the insulation of the furnace body. The benefit of this design is its flexibility; with the use of tube adapters the same furnace can be used with a variety of tube diameters. The HZS three zone tube furnaces offer excellent uniformity which results from division of the heated length into three zones, each with its own controller and thermocouple.


Note: This furnace is modified for use in vacuum and controlled atmosphere
