DESCRIPTION

Resilient and stable unit with built-in industrial PC and touch-screen monitor.

TEST DESCRIPTION

The sample is placed underneath the head. By pressing the "Start“ button the 10 kg weight is lowered onto the sample and presses it flat against the glass-plate.
Then a vacuum pump reduces the pressure in the container to -50,7 kPa. The time is measured it takes to rise to -48,0 kPa (or 29,3 kPa). That time is displayed in Bekk-sec. After 10 sec a preview is shown, to get an impression.
