VDT/S

The VDT/S is a vacuum leak tester for blisters and other packaging forms. The max. vacuum (up to -800 mbar) and the vacuum hold time before release can be set easily via the symbol keypad.

The actual vacuum is continuously displayed.

Test-run parameters can be printed out via an optional printer interface/printer package.

Leak Testing:

With the ERWEKA VDT/S, the blister pack is entered into a vacuum container (150, 200, 250 or 300 mm diameter), which is filled with a methylene blue solution. The vacuum pump is integrated into the control unit of the VDT/S and creates a vacuum in the container (adjustable from -100 to -800 mbar).

As the vacuum pump is switched off, air is sucked into the container and the methylene blue water is sucked into any imperfectly sealed packaging.
Test-run parameters, such as actual/nominal vacuum, hold time etc. can be hard-copied by the optional printer interface-/printer package.

The integrated vacuum pump can be re-calibrated using the optional validation kit which includes a vacuummeter, type DVR.
