Make sure you get the testo 420 volume flow hood for larger ceiling outlets and at the same time enjoy multiple maintenance benefits on HVAC systems. Because the flow hood with the removable measuring instrument is not only exceptionally light, it also guarantees accurate volume flow calculations at swirl outletsUse the testo 420 differential pressure measuring instrument to carry out simple, efficient tests on filters. You can also use the measuring instrument in conjunction with a Pitot tube to measure flow velocity and volume flow really easily in ventilation ducts.

The air flow velocity matrix (in conjunction with the appropriate measuring instrument) is your ideal measurement solution for determining flow velocity and volume flow on laminar flow supply air diffusers.

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.

• Air flow velocity matrix (surface area approx. 360 x 360 mm) - for volume flow measurements on supply air diffusers
• Telescope with spherical head (1800 mm long)
• 2 silicone-free connection hoses (2000 mm long)
• Transport bag
