The hawo InkTest PRO is a new generation of ink tests for the routine testing of sealing seams as per ANSI/AAMI/ISO 11607-1 and ASTM F1929. Any irregularities that occur (e.g. channels) become visible immediately after the single-use cartridge is activated. No pipettes or other tools are needed to fill it. There is no danger of the test liquid dripping or transferring onto other objects.
