8721 0025 Includes Only:
- 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
Features:
- Volume flow measurement on large supply air diffusers, HEPA filters and safety cabinets in cleanrooms
- The telescope makes it possible to carry out measurements on high ceiling diffusers
- Ideal for large surface areas
- Air flow velocity matrix dimensions: 360 x 360 mm
- You can choose to save thermal images as JPEGs
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.
