AIRFLOW™ INSTRUMENTS

At TSI, precision measurement devices are our specialty, and our line of air flow measurement instruments is unbeatable in terms of accuracy. We set high standards, and our end results are top of the line, professional grade instruments. Our respected clientele base includes building service contractors, commissioning specialists, facility engineers and HVAC professionals.

For more than half a century, we have earned a reputation for quality airflow measurement instruments. It began in 1955, when a single airflow measurement and fan design expert founded Airflow Developments Limited. The company was hailed as innovative and reliable and established stringent standards.

Fifty years later, in 2005, TSI acquired the Instrument Division of Airflow Developments. The result expanded the production of highly effective and accurate precision airflow measurement tools. Since then, we have invested in research and development so that we can maintain our place at the head this field. We continue to innovate the best ways to measure air flow and ventilation parameters.
