Duct, Fan, & Stack Field Testing

SCR Tuning Field Test

Efficient and Accurate Flow Measurements

Airflow Sciences Corporation has the equipment and personnel to provide the most reliable flow field testing services.  Available on short notice, our crews can perform a wide range of tests for performance evaluation, emissions, compliance, or equipment guarantees.

  • Velocity
  • Temperature
  • Flow
  • Chemical Species
  • Particulate
  • Pressure


ASC uses high-tech equipment to maximize accuracy and ensure consistent results for all tests.  Velocity testing is performed with the 3DDAS™, a computerized data acquisition system that guides the user through the Method 2 test procedures to ensure success.  The 3DDAS™ takes 1000 readings per second and calculates averages instantly. There are no fluctuating gauges that can result in human averaging; all data is collected electronically.

  • The portable system with remote can reach even the most inaccessible ducts and pipes.
  • Our testing is fully compliant with EPA Methods 2, 2F, 2G and 2H.
  • We can measure velocity, temperature, pressure, and chemical species concentration.
  • Reliable and consistent test results with easy-to-use software.
  • Leak checks are straight forward and documented in the results.
