What type of material is used in constructing a test chamber?

All test chambers use 304 stainless steel.

All test chambers incorporate non-magnetic, welded, type 304 stainless steel inner chambers. The chambers also incorporate cold-rolled steel, a powder-coated exterior, and efficient low "K" factor thermal insulation. A direct drive-shaft powered forced air circulation along with open-wire nichrome resistance elements generate ultimate functionality while maintaining a pleasant laboratory appearance. State-of-the-art regulation techniques result in high accuracy and long-term stability.
