In January 2000, TSI Inc was acquired by JJF Acquisition Inc. TSI Incorporated designs and manufactures precision instruments used to measure flow, particulate, and other key parameters in environments the world over. Backed by unique technical expertise and outstanding quality, TSI serves the needs of industry, governments, research institutions, and universities, with applications ranging from pure research to primary manufacturing. TSI instruments are used around the world - on mountaintops and ocean beaches; in submarines, office towers, factories, and school; in laboratories and on farms. They went to the North and South Poles and served on desert battlefields. They flew in the space shuttle, and one even went to Mars to measure the velocity and direction of Martian winds. TSI instruments help people investigate, identify and solve measurement problems, often plaingy a pivotal role in designing or modifying production processes or testing procedures. They are used in industrial, university, and government facilities in every industrialized country, in nearly every major industry and technical discipline, often in crucial research or control situations. The firm's our particle imaging system helped researchers understand how new airplanes might better handle sudden downdrafts. Our fluid flow instruments were involved in breakthrough research aimed at building a better artificial heart valve. And one of our particle counters sniffed out an open bottle of toxic cleaner in an elementary school, saving the administration from ripping down walls to determine why children were getting sick.
