3. Atmosphere & Safety
   | Parameter | Specification |
   |----------------------|--------------|
   | Applicable Atmosphere | High-purity nitrogen (≤250°C), vacuum (max. 400°C) |
   | Vacuum Leak Rate | ≤0.67Pa/h |
   | Alarm Protection | Audio-visual alarms for overtemperature/thermocouple failure/insufficient water pressure/vacuum anomalies |

4. Structural Parameters
   • Dimensions: 1500×1950×1750mm (including control system)
   • Power Requirements: ≥22kVA, 3-phase 5-wire system (with grounding protection)

III. Key Advantages

1. Research-grade precision: Dual-point temperature control + forced air circulation ensures ±5°C uniformity, ideal for sensitive material processing
2. Multi-level safety protection: Automatic temperature limits for vacuum/atmosphere modes, interlocked shutdown for abnormal conditions
3. Intelligent operation: Touchscreen programming control with process data export and analysis capabilities

IV. Typical Applications

• Vacuum environment: Electronic ceramic sintering, metal powder dehydrogenation (350-400°C)
• Nitrogen protection: MLCC annealing, anti-oxidation treatment of magnetic materials (≤250°C)

V. Precautions

• Strictly avoid exceeding 250°C in nitrogen atmosphere to prevent heating tube oxidation failure
• Regular calibration of thermocouples and vacuum seals is recommended
