TSI, Incorporated

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. Headquartered in Minnesota, TSI has a global network with sales, service, and support locations in the UK, Singapore, China, India, and Germany. Wherever you are, we are there to support you. Since 1961, we’ve set the standards for precision instrumentation and software solutions. Every day our dedicated employees turn research into reality.

The reality for our customers is that they are exposed to respiratory hazards every day. To ensure safety and health, fire departments have respiratory protection programs in place that include fit testing for face masks. TSI’s PortaCount Respirator Fit Testers® deliver safety by utilizing the most effective quantitative fit testing method available to identify poor-fitting masks. PortaCount instruments simplify fit testing with one consistent and objective testing experience across any respirator type.
