The TSI Airflow™ Instruments TA550 is used to measure HVAC system pressures and can be connected to pitot probes for performing duct traverses. Its ergonomic design includes a probe holder and integrated magnets allowing for attachment to exposed ductwork or other metallic surfaces for hands-free operation. The Model TA550 is designed to work with a wide range of plug-in probes for measuring air velocities or IAQ parameters. In addition, the TA550 also includes a built-in workflow for calculating the percentage of outside air, heat flow calculations for testing heating and cooling coils when used with probe Model 964 or 966, and grid guided duct traverse methodologies.
