hawo InkTest PRO
The convenient 4-Sides Ink Test.

hawo InkTest PRO EU

All our professional hawo InkTest systems (hawo InkTest) of the PRO series are dye penetration tests for the routine testing of seal seam integrity based on method A (according to EN ISO 11607-1/ following ASTM F1929-15), also known as 4-side test.

To use the InkTest PRO simply insert one disposable cartridge into the pouch to be tested, seal it and push it open. The 2 ml test liquid is spread evenly over all four sealing seams. This means that the integrity of the packaging can be inspected completely and in a single step.

Any irregularities that may occur (e.g. channels) become visible immediately after squeezing on the disposable cartridge. No further auxiliary equipment such as pipettes is required for the tests. In addition, there is no risk of the test liquid dripping or spilling onto other objects at your workplace or onto your clothing and skin.

Our PRO series test systems are supplied in a specially designed packaging unit (PU = 30 bags of 2 ml), and the aluminum packaging of the disposable cartridges itself ensures that the test solution is protected against sunlight.
