ALPS manufactures systems for non-destructive leak testing of containers and packages and is located in Milwaukee, Wisconsin, USA. Air Logic Power Systems (ALPS) was founded in 1974 and manufactured its first leak tester in 1978. The first high speed rotary system for non-destructive leak testing was supplied in 1985 for the rapidly expanding HDPE plastic container market. In the 1990s, ALPS developed its first electronic leak test circuit and began to focus on non-destructive leak testing for the packaging industry.
