The HTMA series comprises a range of modified atmosphere high-temperature ovens that maintain inert atmospheres up to 700°C. The HTMA ovens come equipped with separate flow controls for purging and process gases, allowing the process gas to be used at lower flow rates after the chamber has been purged of atmospheric air. The switching between purge and process gases can be done manually or by adding an automatic programmable control system. These ovens can achieve oxygen levels down to 50 ppm.
