Grieve - Model BAF-121212-HT -Inert Atmosphere Bench Furnaces
These furnaces are specifically designed for heat treating applications requiring inert atmosphere protection. Inert atmospheres protect the work from oxidation. Precision microprocessor based temperature controls and energy-saving insulation maximize the cost efficiency and performance of these rugged units. Ideal for heat treating of tools, dies and other parts.
