Vacuum Leak Tester is a benchtop leakage tester with an operation panel and a digital LCD display that allows for precise control of the vacuum level and vacuum retention duration. It is also used to assess the effectiveness of specimen seals after compression and falling tests. During the test, an air compressor with a vacuum degree of -90 to 0 kPa is used to compress air. The instrument, which is made of high-quality thickened plexiglass with a thickness of 15 mm, is both safe and simple to use. Vacuum Leak tester is used in the pharmaceutical, medical, daily chemical, electronic compounds, stationary, and other sectors for the purpose of testing for leaks in pouches, bottles, pipes, cans, and boxes of food. Following tests for falling and pressure resistance (compression), specimens are then subjected to leak testing (seal performance).
