TSI imagines, designs, and develops products that solve measurement problems. We collaborate with colleges and universities, research groups, and businesses around the world to set the standard for measurement expertise.

At TSI, our global team strives to provide not only instruments, but also innovative solutions. We operate at both a global scale and a human scale—instruments that measure everything from atmospheric aerosols to the fit of a personal respirator. Turning data into actionable information enables our customers to do their jobs more efficiently. TSI understands the science, the data, and the processes that support your work.
