DIGITAL LEAK TEST APPARATUS
Leak Test Apparatus is a solid state instrument designed for the leakage testing of food, drug and other industrial chemical products. The instrument is used to test the quality of packing processes in strips, blisters and sachets containing tablets, granu lates and liquids. They are also used to check that the seals enclosing the product are perfectly intact. The Instrument is equipped with microcontroller based 4 digit seven segment bright red LED display. Soft touch keys provide a convenient user interface. The unit contains a polycarbonate desiccator housing to sustain the vacuum for long time. A compact vacuum pump for creating high vacuum level in short time period is used. A vacuum gauge on the front panel of the instrument indicates the vacuum level. The vacuum gauge is connected to a control valve that isolates the vacuum inside desiccator from the vacuum source. Test samples to be analyzed are placed into the polycarbonate desiccator housing. A vacuum pump generates vacuum inside the desiccator. Th e vacuum generated is held for a pre-set time, and then released manually. The test samples being analysed should retain their shape during this test, indicating the sealing is correct. Secondly, as the strip/bottles under test are immersed in a coloured dye solution (normally Methylene Blue). The venting of the desiccators will allow any holes to be penetrated by the dye and the contents of the flexible packaging will also be stained with the same coloring material.
