Testo volume flow hood for larger airflows
Testo’s 420 volume flow hood for larger air intakes and outlets is available from BSRIA Instrument Solutions. It lends itself to many different applications, including HVAC in offices and classrooms. It is the lightest model on the market, with a weight of only 2.9 kg.
Built-in flow straighteners pacify the airflow from swirl and multi-way grilles.
The hood can be assembled quickly, and efficient app integration for mobile devices saves the operator valuable time. The adaptable display makes measurement values easy to read.
Battery life is 30 h, and the instrument comes with a range of accessories — including an instrument stand.
