model: GDP-C

Compliant with DIN 53536 and ASTM D1434-82 standard specifications
Using pressure gauge method to test the permeability of dry gas to packaging materials; Under specific conditions, humid gases can also be tested. The sample is placed at the bottom of the testing tank, and the tank is emptied. The permeability can be determined by calculating the pressure increase caused by the gas to be tested penetrating the sample.

The preset emptying time is 10 seconds 48 hours, automatic start test when time is up
Real time display of results on the screen, with a minimum penetration rate of 0.5ml/m2d bar
