Air Velocity Meters

Precise Airflow Measurement with VelociCalc® Air Velocity Meters

For professionals in HVAC, industrial hygiene, and building performance, accurate air velocity measurement is non-negotiable. Whether verifying ventilation system effectiveness, testing fume hood face velocity, or assessing indoor air quality, you need an instrument that delivers reliable data every time. The TSI VelociCalc series of air velocity meters is engineered to provide just that, combining high-accuracy sensors with user-friendly features to streamline your workflow.

Our range of air velocity meters, also known as anemometers, includes thermal and rotating vane options to suit different applications. Thermal anemometers are ideal for measuring low air velocities and performing duct traverses, while rotating vane models are excellent for measuring turbulent airflows. Many of our instruments are multi-functional, capable of measuring not just air speed but also critical IAQ parameters like temperature, relative humidity, and barometric pressure. This integrated functionality allows you to conduct comprehensive environmental assessments with a single, convenient device.

The VelociCalc series is designed for the professional on the go. Ergonomic designs, intuitive interfaces, and features like data logging make them easy to use in the field. With data logging, you can record measurements over time, calculate averages, and easily download the information to generate reports and document your findings. This capability is invaluable for commissioning, troubleshooting, and demonstrating compliance with industry standards like ASHRAE. Choose from our range of straight or articulating probes to access hard-to-reach measurement locations. Trust TSI's air velocity meters to provide the precision and reliability you need to get the job done right.
