Testo 420 Replacement Hood 360 x 360mm
The Testo 420 replacement hood (360 × 360mm) is designed for accurate volume flow measurement at standard square air inlets and outlets. With an integrated flow straightener, it delivers high-precision results even at turbulent diffusers — making it the right choice when your standard 610 × 610mm hood is too large for the outlet you’re testing.
This hood mounts directly onto your existing Testo 420 volume flow hood base and comes with a carry bag. Not sure which hood size suits your diffusers? See our hood selection guide or browse the full flow hood range at HVAC Shop AU.
