Use the air flow velocity matrix to carry out accurate measurements on laminar flow supply air outlets. Use in conjunction with a differential pressure measuring instrument (e.g. testo 420, testo 480 or testo 435-4) to calculate flow velocity and volume flow.

The air flow velocity matrix (360 x 360 mm) can be used over a large area and is particularly suitable for carrying out measurements on HEPA filters and safety cabinets in cleanrooms.

Particularly useful: you can also use the screw-on telescope (can be extended to 1800 mm) to carry out volume flow measurements on high ceiling diffusers.
