Thomas Supplier

Air Velocity Meter

We offer the following ventilation test meter calibration services –


•            Thermo and hot wire anemometers, rotating vane, swinging vane, and pitot style.

•            A2LA ISO 17025:2017 accredited laboratory.    (View our scope here)

•            NIST traceable standards

•            GDJ, Omega, and TSI Wind tunnels capable of going as low as 50 fpm when using orifice plates and up to 9,500 fpm stable flow.

•            Function check of fault sensors

•            Ability to calibrate other sensors RH, Temp, Pressure, CO, CO2

•            Batteries checked and replaced as needed


Ensuring accurate data of your velocity measurement equipment means better ventilation engineering controls for reducing worker exposures.   We, at CIH Equipment, take calibration and repair seriously knowing that workers health & safety are at stake.
