Testo 0699 70771 Air Flow Velocity Matrix

Overview

Use the Testo 0699 70771 air flow velocity matrix to carry out accurate measurements on laminar flow supply air outlets. In conjunction with a differential pressure measuring instrument — such as the testo 420, testo 480 or testo 435-4 — it calculates flow velocity and volume flow. Its large 360 x 360 mm measuring surface makes it particularly suitable for HEPA filters and safety cabinets in clean rooms, and the screw-on telescope, which extends to 1800 mm, lets you reach volume flow measurements on high ceiling diffusers.

Key Features

• Large ~360 x 360 mm matrix for laminar flow outlet measurements
• Screw-on telescope with spherical head, extending to 1800 mm
