Vacuum filling and nitrogen pressure holding testing machine
产品优势
Vacuum Pre-Treatment
Vacuum evacuation prior to testing removes residual air, ensuring consistent nitrogen filling.
High-Precision Pressure Hold
Closed-loop pressure control with real-time pressure-time curves enables slow leak identification.
Multiple Operating Modes
Supports single leak test, cyclic pressure fatigue, and long-term static aging.
Multi-Station Parallel Testing
Standard dual-station configuration, expandable to 4/6/8 independently operating stations.
Full Traceability
Auto-generates PDF/Excel reports with barcode binding and MES network integration.
Safety Pressure Relief
Automatic pressure relief upon overpressure, emergency stop, overload and insufficient air supply protection.
