Introducing the Leakage GB-M1 Sealing Tester from Hylec Controls – a state-of-the-art solution powered by compressed air and equipped with a high-precision electronic pressure sensor for assessing the sealing process and performance of flexible packages. Employing microcomputer control, this advanced tester offers a comprehensive evaluation, providing scientific insights crucial for determining technical requirements in industries such as food, pharmaceuticals and daily chemicals.

Test Principle Evacuating the vacuum chamber induces a pressure difference between the inside and outside of the water-immersed sample. The observation of gas escape or water infiltration enables precise judgment of the sample's sealing performance.

Standard Compliant with ASTM D3078.
