Leak detection

High voltage can be used for much more than increasing the surface tension of a subject. By utilizing the principle that a voltage between two electrodes will always seek the shortest path, Tantec’s electronics engineers have thus developed a special technology that allows detection of gaps up to 3 microns.

LeakTEC can be used for nonconductive materials and is particularly suitable for quality testing cast and welded joints in medical instruments such as pipettes, needles, containers, etc. The test is fully automatic and can be carried out at even very high production speeds. Via a digital interface, LeakTEC can be integrated with an existing production line so that defective items can be automatically segregated from the other items
