We offer both commercial and accredited anemometer calibrations.

Our Capabilities include:

  • Anemometers 

  • Air Velocity Meters 

  • Rotary Vane Anemometers 

  • Hot Wire Anemometers 

  • Ultrasonic Anemometers 

  • Velocity Probes 

Over the years we have invested in not just one but two wind tunnels to support anemometer calibrations.

Our Airflow Open Jet Wind Tunnel has a flow rate of 500 to 6,000 fpm (2.54 to 30.5 m/s). This wind tunnel is designed to calibrate rotary vane type and ultrasonic anemometers.

Our Omega WT4401 Wind Tunnel has a flow rate of 500 to 9,000 fpm (2.54 to 45 m/s). This wind tunnel is designed to calibrate hot wire type anemometers. 

Using our Dwyer 167-6 Pitot Tube, we are able to measure the velocity from 500 to 9,000 fpm (2.54 to 45 m/s) with an uncertainty of 1% of reading. This is designed to calibrate all types of anemometers.

Anemometer Calibration

  • “I have used Essco for calibration services while employed with various companies over the years. I have always been happy with their responsiveness and their prices overall are competitive. Communication is great… One of the first things I did as a new employee was bring Essco in as our main calibration supplier. Everyone is happier since I made the switch, but no one is happier than I am. I recommend Essco without reservation and will always consider bringing them in to any potential future employers too.”
