Bestech Australia SealTick leak testing system

Click2Contact

The SealTick TSE6086B leak testing system from Bestech Australia has been developed to enable testing of seals in food and pharmaceutical packages. It works on the principle of vacuum decay, where a pressure difference will generate a leak flow from higher pressure to lower pressure. A testing package is rapidly placed under a vacuum and then isolated, so that any leaks allow a return to atmospheric pressure.

The test is dry, clean and objective, simple to operate, rapid (5-15 s) and highly sensitive. It is effective and safe even when the product protrudes and is non-destructive, so the product goes straight back on the packing line.

The system’s stainless steel construction is suitable for a production environment and it accepts a wide range of pack sizes and shapes without adjustment. The test results shown on lamps - pass; fine fail; coarse fail - and displays the quantitative result on a backlit display.

The test includes 20 nameable methods and has a memory capacity for 30 days of results (1 file/day). The Ethernet connection allows periodic upload for mandatory record keeping and trend identification, plus online monitoring via web browser. Test parameters are stored and accessible under password access and the setting and control of test times and parameters is done from the keyboard.

The test vacuum is internally generated from compressed air with a high resolution measurement of leak rate. The system accepts items up to 360 x 300 mm (depending on thickness).
