Air Velocity Meter Rentals

Instruments in this category measure air velocity or volume for use in testing and balancing indoor air ventilation systems. Many of these models are also capable of measuring addtional ventilation or indoor air quality parameters including temperature or pressure.

TSI VelociCalc

Air Velocity Meter

Featured Rental

Magnify

Simple to use and with advanced functionality for more complex tasks, the VelociCalc is our most popular air velocity rental instrument. Not only are air velocity, differential pressure, humidity and temperature directly measured, but the instrument is also capable of calculating volumetric flow and dew point. All of these capabilities combined with features like a telescoping probe and clearly labeled controls, make the VelociCalc the standard in handheld anemometers.
