Airflow
Testo
Testo airflow instruments for supply and return air: the 420 capture hood at the register and the 425 hot-wire anemometer in the duct, both reporting to measureQuick over Bluetooth.
Testo's airflow line covers the two places airflow gets measured on a residential or light-commercial system. The testo 420 capture hood reads cfm directly at supply registers and return grilles. The testo 425 thermal anemometer traverses the duct through a test port with a telescoping hot-wire probe. Both connect to measureQuick over Bluetooth. The 405i hot-wire and 410i vane anemometer Smart Probes are listed in the Testo Smart Probes line.
