Differential Pressure Leak Tester axis 677 measures the differential pressure loss (ΔP) between the test part and reference volume over a fixed time. Determines pressure loss during the test.

Improvement Over Pre-decessor Axis 677

• 2x faster leak detection speed.
• 30% reduction in device size and weight.
• Redesigned user interface.
• Expanded data storage: 50,000 to 100,000 records.
• Integrated internal calibration master.
• High-precision accuracy.
• Advanced signal processing.
• Storage for 128 distinct part programs.
• PC communication for advanced data logging.
• Ethernet connectivity support.

HELIUM LEAK TESTING OF SPACECRAFT & SATELLITE PROPELLANT TANKS

WHY LEAK TESTING IS CRITICAL

• Manufacturing & assembly
• Pressure & vacuum conditions
• Launch vibration & acceleration
• Long-duration operation in space
• Thermal cycling
• Extended propellant storage
