for packaging


The VDT/S is a vacuum leak tester for blisters and other packaging forms. The max. vacuum (absolute pressure range up to 300 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 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 (absolute pressure range from 100 to 300 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 printer interface-/printer package. The integrated vacuum pump can be re-calibrated using the optional validation kit which includes a vacuummeter, type DVR.
