Introducing the Leakage GB-M Sealing Tester by Hylec Controls – an innovative solution utilising compressed air and high-precision electronic pressure sensors for assessing the sealing process and performance of flexible packages. This cutting-edge tester, under microcomputer control, provides invaluable scientific insights, aiding in determining technical requirements for diverse industries such as food, pharmaceuticals and daily chemicals.

Test Principle The tester evacuates the vacuum chamber, inducing a pressure difference between the inside and outside of the sample immersed in water. The observation of gas escape or water infiltration enables a precise judgment of the sample's sealing performance.

Standard Compliant with ASTM D3078.
