The GT-N69C Leak and Sealing Tester is a specialized instrument for quantitatively determining the sealing and strength performance of various packaging. It measures sealing strength, expansion pressure, and leakage of bags; the sealing of plastic anti-theft caps and flexible tubes; as well as the compressive, breakage, and torsional strength of caps and packaging materials. The system utilizes a positive pressure test principle with stable mechanical control, offering multiple test modes (rupture, creep, pressure preservation) and customizable ranges (standard 0-600 KPa) and fixtures. It is designed to meet relevant international and industry standards.
