Description
1. Closed-Loop Ultra-Clean Environment Protection: - Glovebox Active Protection: Provides an initial, reliable ultra-low water and oxygen environment (H₂O & O₂ < 0.1 ppm) for safe sample pretreatment and loading. - Seamless Sample Transfer: Enables contamination-free transfer of samples between the glovebox and the furnace via a dedicated transition chamber, completely isolating them from the atmosphere. 2. Precise Application of Extreme Conditions: - Vacuum and Atmosphere Protection: The furnace body is equipped with vacuum extraction capability and can introduce high-purity inert gas. By following the classic logic of "first evacuate, then backfill with atmosphere," it ensures a dual guarantee of an oxygen-free environment inside the furnace. - Automatic Lifting and Precision Temperature Control: The furnace lid is automatically lifted via an electric mechanism, linked with a programmable logic controller (PLC) to ensure accurate and repeatable operation. Combined with multi-stage programmable temperature control, it enables complex sintering processes. 3. Intelligent Integrated Control
