Manage dew point and oxygen concentration to prevent oxidation, modify, and pre-treat metal surfaces.

In the surface treatment of metal parts and powder materials, not only temperature but also ambient gas, dew point, oxygen concentration, and treatment time significantly affect the surface condition and quality. In particular, for oxidation prevention, surface modification, coating pretreatment, and hydrophilization/hydrophobicity treatment, it is important to reproducibly examine conditions while switching between dry, humid, and reducing atmospheres. Our multi-atmosphere furnace can switch between various ambient gases such as N2, Ar, Air, H2, and NH3 after displacing the air in the furnace through vacuum replacement. Additionally, by connecting a Wetter, it is possible to manage surface treatment conditions with controlled humid atmospheres and dew points. 【Features】 ■ Capable of switching to various gas atmospheres after vacuum replacement ■ Supports humid atmosphere and dew point control through Wetter connection ■ Can manage atmosphere history such as dry → humid → dry ■ Applicable for oxidation prevention, surface modification, and pretreatment of metal surfaces ■ Condition management combining dew point meters and O2 meters can also be considered *For more details, please download the materials or contact us.
