We performed Air Velocity Measurement / tests to determine the average filter face velocity and uniformity, and the average room airflow velocity and uniformity within a clean room. The average airflow velocity is calculated by dividing the total of the airflow grid velocities by the number of readings taken.

ACPH tests determine the total air volume get in to a clean room. The use of TSI Accubalance Air Capture Hoods of Model No.8380, assures accurate test results. The hood measures air volume flowing through diffusers and grills, these air capture hoods are easy to use. These hoods simply hold Perimeter edge to a diffuser or grill and read direct supply or exhaust airflow on the micro meter display.
