Description

The Testo 420 volume flow hood is a lightweight balometer-style capture hood for HVAC technicians who balance ceiling and wall outlets quickly and repeatably. MME stocks genuine Testo air-measurement tools with UAE support for commissioning contractors and facilities teams.

Use case: on a fit-out handover, the technician seats the 610 × 610 mm hood on a diffuser, lets the integrated flow straightener settle turbulent air, and logs supply/extract volume flow between 50 and 4000 m³/h via the Bluetooth app. Shop air flow instruments, visit the Testo brand page, and read our Testo 410-1 vs 410-2 anemometer review for complementary velocity measurements.
